Fill in the blanks using the correct tenses of the verbs given in brackets and choose the right answer from among the options given below them:    I _______ my friend last week (meet)

Explanation: (a) had met: This is the past perfect tense, which is not necessary in this context. Past perfect is used to indicate an action completed before another past action, but it's not required here. (b) meet: This is the base form of the verb, and it does not fit the past time frame indicated by "last week." (c) have met: This is the present perfect tense, which is used to connect the past with the present. It is not the most appropriate choice for a specific past action that occurred last week. (d) met: This is the simple past tense, and it is the correct choice for describing an action that happened in the past, specifically last week in this context.
