Detailed Solution

Given, a quadrilateral ROPE as shown below,
Question Image

Adjacent angles are the angles which share a common edge of a quadrilateral.
In other words, the angles which lie on one side of a quadrilateral are known as adjacent angles.
Now, from the given diagram, we can observe that

∠ R, ∠ O; ∠ O, ∠ P; ∠ P, ∠ E

and

∠ E, ∠ R

, all lie on the same sides, viz., RO, OP, PE and ER respectively.
So, by definition, these are the pairs of adjacent angles.
Hence, the correct option is (1).
