Final answer:
The sentence with pronoun consistency issues is 'Every time I go to Wal-Mart, you can never find a close parking space.' The inconsistency is in the shift from first person 'I' to second person 'you'. The correct option of choice is option b.
Step-by-step explanation:
The sentence that lacks pronoun consistency is:
b. Every time I go to Wal-Mart, you can never find a close parking space.
This sentence starts by talking about 'I', which refers to the speaker, but then switches to 'you', implying a general statement that can apply to anyone. The shift in pronouns from first person to second person within the same sentence leads to inconsistency.
