Three words in bold are given, which have something in common among themselves. Out of the four given alternatives, choose the most appropriate description of these three words: voodoo, sorcery and necromancy.

Introduction / Context:
This question checks your awareness of specialised vocabulary related to the occult and supernatural beliefs. The three given words are voodoo, sorcery and necromancy. All of them appear in literature, folklore and discussions about magic or supernatural practices. The task is to identify the description that correctly captures what they all have in common, not just something that applies to one of them in isolation.

Given Data / Assumptions:

• The three terms are voodoo, sorcery and necromancy.
• We assume their standard, widely accepted meanings in English.
• Each word is connected to some kind of magical or supernatural practice.
• We are looking for a broad category that includes all three practices.
• The correct option must apply clearly and directly to each of the three words.

Concept / Approach:
The best way to approach this question is to recall the domain in which each word is typically used. Voodoo is known as a form of religious and magical practice, often associated with rituals, spells and spirits. Sorcery is a general term for the use of magic, especially for harmful or selfish purposes. Necromancy is specifically the practice of communicating with or summoning the dead, often seen as a form of dark or forbidden magic. The common thread is that all three terms are linked to black magic or dark occult practices.

Step-by-Step Solution:
Step 1: Recall that voodoo involves ritualistic magic, spells and spirit worship, often portrayed as dark or dangerous in popular culture. Step 2: Recall that sorcery refers broadly to the practice of magic, especially when used to influence events or people in mysterious or harmful ways. Step 3: Recall that necromancy specifically focuses on contact with the dead, raising spirits and predicting the future through them, which is treated as a form of black magic. Step 4: Examine whether any of the given options describe a category that covers voodoo, sorcery and necromancy together. Step 5: The description that they are terms connected with black magic clearly unites all three, since each involves occult, forbidden or dark magical practices. Step 6: Confirm that no other option fits all three words at the same time.

Verification / Alternative check:
The other options can be quickly tested. None of these words is the name of an ancient script; scripts refer to writing systems like hieroglyphics or cuneiform, not magical practices. They are also not arts found in sculptures, although some sculptures may depict scenes inspired by such practices. Finally, they are not means of communication in the sense of languages or signals used in daily life; rather, they describe occult practices that attempt supernatural influence or communication with spirits. Hence, the only fully accurate category is that they are terms related to black magic.

Why Other Options Are Wrong:
Calling them ancient arts found in sculptures confuses practice with depiction. Sculptures may show magical scenes, but the terms themselves are not sculptural arts. Referring to them as ancient scripts is incorrect because they do not refer to writing systems or alphabets. Describing them as prehistoric means of communication is also wrong, since they are not languages but magical practices.

Common Pitfalls:
A common error is to rely on partial knowledge and assume that voodoo alone defines the set, without fully considering sorcery and necromancy. Another mistake is to overthink the historical or artistic angle, even though the words clearly belong to the domain of occult magic. Whenever three words of this type appear, it is useful to zoom out and ask which broad area of knowledge they all share, rather than focusing on the exact rituals or regions associated with each practice individually.

Final Answer:
Voodoo, sorcery and necromancy are all terms connected with black magic.
