Select the most appropriate option to fill in the blank. The old Neem tree…

Correct answer: had stood

Explanation –

The relative clause describes a state that lasted for fifty years and ended when the tree crashed last night. Because we are relating one past situation (the tree standing for fifty years) to another past event (the crash), we use the past perfect tense to place the longer-lasting state before the past event.

• Use past perfect (had + past participle) to describe an action or state that existed before another past event.

• The phrase "for fifty years" indicates duration up to the past event, so past perfect is appropriate to show that the standing continued until the crash.

Why the other choices are incorrect:

• "has stand" is ungrammatical. The correct present perfect form would be "has stood," but present perfect links the past with the present and is not used to relate one past situation to another past event.

• "is standing" is present continuous and describes an action happening now; it cannot express a state that existed up to a past event.

• "stands" is simple present and indicates habitual actions or general truths, so it does not fit a past narrative about a one-time event.

Correct usage example: The old Neem tree which had stood in our compound for fifty years crashed to the ground last night.
