Which antecedent agrees with the pronoun in this sentence? Select the correct answer from the list.

___ is best known for her oatmeal cookies
A.martha
B.the smith's
C. Jim
D. Avery and Michelle

A. Martha

The correct answer is A. Martha.

To determine which antecedent agrees with the pronoun in the sentence "___ is best known for her oatmeal cookies," we need to identify the pronoun and match it to its antecedent.

The pronoun in the sentence is "her," which is a possessive pronoun referring to a female person.

Now, let's go through the options:

A. Martha - This is a singular female name, and since the pronoun "her" is also singular and feminine, Martha could be a potential antecedent that agrees with the pronoun.

B. The Smith's - This is a plural possessive noun, referring to a family. Since the pronoun "her" is singular, it does not agree with a plural antecedent. Therefore, "The Smith's" is not a correct answer.

C. Jim - This is a singular male name. Since the pronoun "her" is feminine, it does not agree with the antecedent "Jim." Therefore, Jim is not a correct answer.

D. Avery and Michelle - This is a plural dual-antecedent, consisting of two people. Since the pronoun "her" is singular, it does not agree with a plural antecedent. Therefore, Avery and Michelle are not a correct answer.

Based on the analysis, the correct answer would be A. Martha, as both the pronoun "her" and the antecedent "Martha" are singular and feminine.
