Choose the most appropriate option to complete the given sentence:-

Though Abha _____ the manuscript several times before submitting it to the publisher, yet a major error came to light.

had reviewed

The correct answer is Option (3) → had reviewed

The sentence describes two actions that happened in the past:

1. Abha reviewing the manuscript.

2. Abha submitting the manuscript (and the error coming to light).

When one past action is completed before another past action, we use the Past Perfect Tense (had reviewed) for the earlier action, and the Simple Past Tense for the later action (submitted).

• Earlier Action (Past Perfect): Abha had reviewed (completed before submission).

• Later Action (Simple Past): (before) submitting it.
