Step by Step Solution
Step 1
Two angles are complementary angles when these angles add to 90°. Hence, angle I and II are complementary angles. This is because 55° add with 35° gives 90°.
Step 2
As for angle III and IV, they are also complementary angles. This is because when we add 25° with 65°, we get 90°.
Step 3
Clearly, I-II and III-IV are complementary angles. Hence, the answer is B.
