MCQ
The pair of complementary angles from the following options are:
  • A
    $30^\circ , 150^\circ$
  • B
    $76^\circ , 14^\circ$
  • $65^\circ , 65^\circ$
  • D
    $120^\circ , 30^\circ$

Answer

Correct option: C.
$65^\circ , 65^\circ$

Complementary angles are those, whose measures add up to $90^\circ $ Out of the given options,
$30+150=180^\circ\neq90^\circ76+14=90^\circ\\65+65=130^\circ\neq90^\circ120+30=150^\circ\neq90^\circ$
