Choose the right tense. My friend -- before I came.

সঠিক উত্তর: had left
ব্যাখ্যা: "Had left" is in the past perfect tense, which indicates that the action of leaving was completed before another action (the speaker’s arrival).

ভুল অপশন ১: would be leaving
ব্যাখ্যা: "Would be leaving" is incorrect because it suggests an ongoing future action, which does not fit with the context of something that happened before the speaker came.

ভুল অপশন ২: had been leaving
ব্যাখ্যা: "Had been leaving" suggests a continuous past action but does not fit the simple completion implied in this context.

ভুল অপশন ৩: will leave
ব্যাখ্যা: "Will leave" is in the future tense, which is inappropriate since the sentence refers to an event that happened before the speaker arrived.
