The correct answer is option (A):
resembles his mother
The sentence "The child closely resembles to his mother" contains a common grammatical error. The verb "resemble" is a transitive verb, meaning it directly takes an object without the need for a preposition like "to" or "with". Therefore, the correct way to phrase this is "The child closely resembles his mother." Looking at the options provided:
* "resembles his mother" - This is the correct form because "resembles" directly takes "his mother" as its object.
* "resemble mother" - This option is incorrect because it uses the plural form "resemble" which doesn't agree with the singular subject "child". Also, "mother" is a common noun and usually requires a possessive determiner like "his" or "her" when referring to a specific individual.
* "resemble with his mother" - This is incorrect as "resemble" does not take the preposition "with".
* "resembles to mother" - This is incorrect because "resemble" does not take the preposition "to".
Therefore, the option "resembles his mother" is the grammatically correct replacement for the underlined part of the sentence.
