Lets look at the question is asking:
They are looking for adjacent angles.
The geometrical definition for adjacent is neighboring.
So with this we can tell that They are looking for neighboring angles.
The adjacent/neighboring angles are
∠1 and∠2 and ∠3 and ∠4.
So since ∠3 and∠4 are not an option, we can make an educated guess that the answer is A.
(I feel slightly confused on this question, so if it wrong I am truly sorry!)
I hope this helped :)
