Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. relentlessly.
The context shows Shan’s sister was worried and persistent when knocking at the door because he hadn’t come out all day.
Option 1 – sincerely: Means with honesty or truthfulness, which does not describe the manner of knocking.
Option 2 – unconsciously: Means without awareness, which does not fit the anxious and deliberate action here.
Option 3 – conscientiously: Means with great care and attention to detail, which is more suited to careful work, not urgent knocking.
Option 4 – relentlessly: Means without stopping or giving up — exactly how an anxious person would knock in such a tense situation.
