Solution

Two adjacent angles are said to form a linear pair of angles if their non-common arms are two opposite rays.
In the given below figure, OB is a common ray. OA and OC are two non-common arms in an opposite directions.
$∠ 2 and ∠ 1$ are adjacent angles.
Hence, the correct answer is opposite rays.
