Final answer:
The sentence with an error is b. 'Last year, the company rents a warehouse to store excess production,' where 'rents' should be in the past tense 'rented'.
Step-by-step explanation:
The sentence that contains at least one error is option b: Last year, the company rents a warehouse to store excess production. The error in this sentence is a mismatch in tense. The phrase 'last year' suggests that the action happened in the past, so the past tense 'rented' should be used instead of the present tense 'rents'. The correct sentence should be: Last year, the company rented a warehouse to store excess production.
