The correct answer is:
D. Chris is adamant in his belief that anyone who puts forth the effort - no matter their age- is able to train and complete half-marathon
Explanation:
A pronoun-antecedent error, also known as pronoun-antecedent disagreement, is a common mistake in English, and it is made when the pronoun (antecedent) doesn't match or agree with the noun. In this case, the pronoun "anyone" is a singular indefinite pronoun; which means that the word "their" disagrees with the noun, and it should be replaced to "his or her".
The correct sentence would be:
- Chris is adamant in his belief that anyone who puts forth the effort- no matter his or her age - is able to train and complete half-marathon.
