Answer:
The answer is B.
Step-by-step explanation:
A shift in person refers to starting a sentence with one pronoun and then suddenly changing it to another. It is considered a grammatical error and could also sound a bit confusing for the reader.
In answer A we have a shift from he to you, however they are not in the same sentence.
Answer B has the shift from we to you in the same sentence which can be classified as a shift in person and should be corrected by using the same pronouns.
Answer C - athletes is a plural form and since we are talking about athletes generally, we use third person plural, so in this case, the word athletes serves as an antecedent for the pronoun they, so there is no pronoun shift.
Answer D - one is a pronoun that is, although can refer to both singular and plural, grammatically is always singular, most usually in the third person. Since Avilon is the subject of the rest of the sentence, there is no shift in person.
