To correct the pronoun issue in the sentence about becoming a doctor, which phrase should be used?

The phrase "If somebody wants to become a doctor, he or she must be" effectively addresses the pronoun issue in the sentence. This construction uses "he or she" to clearly indicate that the subject may be either male or female, thereby avoiding any ambiguity in the pronoun's reference. It also maintains grammatical consistency with the singular noun "somebody," which aligns with the idea of representing an individual regardless of gender.

The other choices either compromise the grammatical structure of the sentence or do not adequately address the issue of inclusivity. For example, the other options that use "they" may be considered less formal in certain contexts or less clear as they suggest a plural reference, while "want to become" in one of the phrases grammatically disrupts the structure of expressing desire. In contrast, option C maintains clarity and correctness, ensuring that the statement remains both inclusive and grammatically sound.
