Which of the following is/are incorrect ?

(A) $\sin 0^{\circ}=0$
(B) $\tan 0^{\circ}=0$
(C) $\cos 0^{\circ}=0$
(D) $cosec ~0^{\circ}=0$
(E) $\sec 0^{\circ}=0$

Choose the correct answer from the options given below:

(C), (D) and (E) only

(A) $\sin 0^{\circ}=0$
(B) $\tan 0^{\circ}=0$
(C) $\cos 0^{\circ}=0$
(D) $cosec ~0^{\circ}=0$
(E) $\sec 0^{\circ}=0$

we know that,

$\sin 0^{\circ}=0$

$\tan 0^{\circ}=0$

$\cos 0^{\circ}=0$

Among all of them, only c, d, and e are incorrect others are correct.

The correct answer is Option (4) → (C), (D) and (E) only
