Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. wandering.
The word "wandering" is the correct choice for blank (2) because it is a verb that describes the action of thoughts drifting away from focus.
"Wandering" fits this requirement, indicating a lack of concentration while studying. The other options do not grammatically match the context of thoughts losing focus.
