(B) respect - respective
(C) neat - neatly
(D) complete - completion
(E) prefer - preference

Choose the correct answer from the options given below :

(C) Only

The correct answer is: Option 3: (C) Only

Beautiful - Beautifully: This pair represents an adjective and its corresponding adverb. They share the same root word ("beautiful") but with different grammatical functions. "Beautiful" describes a noun ("a beautiful flower"), while "beautifully" describes a verb ("sing beautifully").

• (A) beauty - beautify: While related, they are not the same as "beautiful - beautifully." "Beauty" is a noun, while "beautify" is a verb. They don't share the same root word ("beauty" vs. "beautify") and differ in grammatical function.
• (B) respect - respective: This pair also doesn't match the relationship of "beautiful - beautifully." "Respect" is a noun, while "respective" is an adjective. They are not formed from the same root ("respect" vs. "respective") and have different grammatical roles.
• (D) complete - completion: Similar to (A), they are related but not identical. "Complete" is an adjective, while "completion" is a noun. They don't share the same root ("complete" vs. "completion") and differ in grammatical function.
• (E) prefer - preference: This pair also doesn't exhibit the same relationship. "Prefer" is a verb, while "preference" is a noun. They are not derived from the same root ("prefer" vs. "preference") and have different grammatical roles.

Only neat - neatly shares the same relationship as "beautiful - beautifully." Both are formed from the same root word ("neat") with different grammatical functions: "neat" as an adjective and "neatly" as an adverb.
