In English spelling, choose the correctly spelt form of the word "forcibly" from the options given below.

Introduction / Context:
Spelling questions in English often test how well a learner understands common patterns for forming adverbs from adjectives. The word forcibly is a regular adverb that comes from the adjective forceful or the noun force, and it is frequently used in written English in the context of law, police action, and everyday description. Knowing the correct spelling helps in reading comprehension and clear written communication for competitive exams and general usage.

Given Data / Assumptions:

• The base word is force, which ends with the silent letter e.
• We need to select the correctly spelt adverb meaning by force or in a forceful way.
• Four slightly altered spellings are given as options.
• Standard English spelling rules for adverbs ending in ly apply.

Concept / Approach:
When an adverb is formed from a word ending in a silent e, the usual rule is to drop the final e before adding the suffix. For example, force becomes forcible and forcibly, just like notice becomes noticeable. We should identify which option follows this rule and also looks like a standard, familiar spelling in English dictionaries and exam material. Forms that insert extra vowels or disturb the consonant order are usually incorrect variants meant to confuse the learner.

Step-by-Step Solution:
Step 1: Identify the base word, which is force, a common English word. Step 2: Recall that the usual adjective is forcible and the adverb is forcibly. Step 3: Apply the rule that the final silent e of force is dropped before adding ibly. Step 4: Compare each option and see which one matches the correct pattern forcibly. Step 5: Confirm that forcibly is widely accepted in standard English usage.

Verification / Alternative check:
A quick mental check is to place the word in a sentence such as The protesters were forcibly removed from the area. Only forcibly looks natural and familiar in this context. You can also compare with similar adverbs like possibly, visibly, and sensibly, all of which follow the consonant plus ibly pattern. This confirms that the correct spelling retains the consonant cluster c and b together while dropping the final e from force.

Why Other Options Are Wrong:
Forceibly adds an extra e after c, which breaks the standard pattern for forming adverbs from words ending in e and looks awkward in a sentence.
Forciebly changes the order of the vowels, placing ie, which does not match any standard dictionary spelling of the word.
Fourcibley inserts extra letters and changes the base word too much, so it no longer matches the spelling of force at all.

Common Pitfalls:
A common mistake is to keep the silent e in the root word and still add the full adverb ending, which produces forms like forceably or forceibly. Another error is to confuse the spelling pattern with other words that use ei or ie, which leads to wrong combinations like forciebly. Learners should remember that the base word force simply drops its final e and then takes the ending ibly, creating forcibly.

Final Answer:
The correctly spelt form of the given word is Forcibly.
