Answer: "My brother ran to the store yesterday" is the grammatically correct sentence.
Explanation: In this sentence, "ran" is the correct form of tense. All verbs exist in three tenses, past, present and future.
The past tense is used for events that have already occurred (e.g., last week, yesterday, a month ago). The present tense is used for events that are happening right now or for processes that are continuous (e.g., reads, walks, revolves). The future tense is used for events that are expected to happen in the future (e.g., soon, later, day after tomorrow).
The past is being discussed in this sentence. This is clear from the word "yesterday" and it means that the incident has already occurred. Hence, "ran" is the appropriate form of verb and "My brother ran to the store yesterday" is the correct sentence.
