I am sure with my answer.
For 'a'
If we take 2 acute angles (0° > 90°), 40° and 50°
A pair of angles is said to be complementary when their sum is 90°.
To check 'a',
40° + 50° = 90°
90° = 90°
A pair of acute angles can be complementary.
For 'b'
If we take 2 obtuse angles (90° > 180°), 100° and 115°
A pair of angles is said to be complementary when their sum is 90°.
To check 'b',
100° + 115° = 215°
215° ≠ 90°
A pair of obtuse angles can never be complementary.
For 'c'
If we take 2 right angles (90°)
A pair of angles is said to be complementary when their sum is 90°.
To check 'c',
90° + 90° = 180°
180° ≠ 90°
A pair of right angles can never be complementary.
For 'd'
If we take a obtuse and a acute angle (91 and 1)
A pair of angles is said to be complementary when their sum is 90°.
To check 'd',
91° + 1° = 92°
92° ≠ 90°
A pair of a obtuse and a acute angle can never be complementary.
