Which of the following sentences uses correct verb tense?

The sentence "He eats breakfast at 7 am every day" correctly uses the present simple tense to describe a habitual action. The present simple tense is ideal for expressing routines and regular occurrences, making it appropriate for talking about daily habits like having breakfast.

In contrast, the other options present issues with verb tense usage. For instance, the first option refers to an action happening in the past but uses an ongoing form that is awkward and incorrect for a completed action like going to the store yesterday. The third option incorrectly mixes future tense with a past time reference, suggesting something that cannot logically connect. The last option misuses the future tense with an incorrect form of the verb "finish," using "finishing" instead of "finish." Thus, option B stands out as the only sentence that correctly employs its verb tense for the context provided.
