Fill in the blank with the appropriate Phrasal Verb from the options…

The correct answer is Option (2) → drop in

A phrasal verb is a verb joined with a small word such as up, out or together. The two words together have a new meaning.

The speaker is asking whether it is all right to visit briefly for a cup of tea.
Complete sentence: I thought I would drop in for a cup of Tea. Is that fine?

Phrasal verb	Meaning	Example
(1) drop off	to fall asleep or to leave someone or something at a place. Neither meaning fits a visit for tea.	The school bus will drop off the children at four.
(2) drop in (answer)	to pay a short, informal visit, often without arranging it in advance	Do drop in whenever you are in our area.
(3) drop	to let something fall or to give something up. "Drop for a cup of tea" is not used.	Be careful not to drop the plates.
(4) drop out	to leave a course, a race or a group before the end.	He had to drop out of college because of illness.

Note: In the original NTA paper, Option 3 read "drop by". NTA accepted this option as a correct answer as well. To leave only one correct answer and avoid confusion for students, it has been changed here to "drop".

Advice for the exam: In the real exam, mark the answer that is grammatically or factually correct. If NTA’s provisional answer key marks a different option, challenge it during the answer-key challenge window and give the reason in one or two lines.
