He was an irresponsible person to the matter of taking up responsibilities.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. in the matter of taking up.
"In the matter of" is correct because it refers to a specific issue or concern—in this case, taking up responsibilities.
The preposition "in" fits the context, while other options (at, by, along) are incorrect for this usage.
