Answer:

Option 1 is correct.

Step-by-step explanation:

Given If the cos 90° = 0, then the value of sin 0° is

As cos Ф=sin(90-Ф)

because angles are complementary i.e Ф+(90-Ф)=90

∴ cos 90° = sin(90-90)°=sin 0°

cos 90°=0 gives sin 0°=0 as cos 90°=sin 0°

because the angles are complementary i.e 90°+0°=90°

Hence, option 1 is correct
