Solution

The correct option is C complementary
Two angles are called complementay angles if the sum of their measures equals 90°.

For example:
Here, $∠ A O D = 30^{o}$ and $∠ D O B = 60^{o}$ .
$∠ A O D + ∠ D O B = 30^{o} + 60^{o} = 90^{o}$

So. $∠ A O D$ and $∠ D O B$ are complementary angles.

The correct option is C complementary Two angles are called complementay angles if the sum of their measures equals 90°. For example: Here, ∠AOD=30o and ∠DOB=60o. ∠AOD+∠DOB=30o+60o=90o So. ∠AOD and ∠DOB are complementary angles.
