In the following question, a word has been written in four different ways. Select the correctly spelt word.

Introduction / Context:
This spelling question tests your ability to recognise correct standard English spelling among several incorrect variants. You are given a set of words, most of which are misspelt or not standard words. Your task is to identify the correctly spelt word used in modern English.

Given Data / Assumptions:

• Options: "humanoid", "spiling", "amigrate", "referrent", "huminoid".
• We must select the one word whose spelling is correct and widely accepted.
• We assume general vocabulary knowledge (no highly technical spellings).

Concept / Approach:
"Humanoid" is a standard English word meaning having an appearance or character resembling that of a human. It is correctly spelt with "humano-" + "-id". The other options either do not exist as standard English words ("spiling", "amigrate", "huminoid") or are incorrect spellings of known words ("referrent" should be "referent"). Therefore, "humanoid" is the only correct option.

Step-by-Step Solution:
Step 1: Check each word against known vocabulary. "Humanoid" is a familiar term in science fiction and robotics.Step 2: Examine "spiling": not a common English word; the likely related word is "spilling" or "spoiling".Step 3: "Amigrate" does not match any common verb; the standard verb is "migrate".Step 4: "Referrent" resembles "referent", the correct spelling for something referred to by a word; note the single "r" in the middle.Step 5: "Huminoid" is a misspelling of "humanoid". Thus, "humanoid" is clearly the only correctly spelt choice.

Verification / Alternative check:
Use "humanoid" in a sentence: "The robot had a humanoid form." This looks and sounds right, and you can find this spelling in dictionaries and science fiction descriptions. Try the others: "The robot had a huminoid form" or "He is a referrent" clearly look wrong to anyone familiar with written English. This confirms that "humanoid" is the standard spelling.

Why Other Options Are Wrong:

• spiling: Not a standard word; the common form for dropping liquid is "spilling".
• amigrate: No such standard verb; the correct word is "migrate".
• referrent: Misspelling of "referent", which has only one "r" after "fe".
• huminoid: Misspelt version of "humanoid", with "ni" instead of "an".

Common Pitfalls:
Students sometimes assume that the most unusual or unfamiliar word must be correct. However, exam setters often include such trick options deliberately. Whenever possible, rely on words you recognise from reading. If you recall seeing "humanoid" in books, articles, or movies, that is a strong clue that it is the correct choice.

Final Answer:
The correctly spelt word is humanoid.
