Answer:

B

Explanation:

1. The function
y=\cos^(-1)x has the domain:


-1\le x\le 1.

2. The function
y=\sin^(-1)x has the domain:


-1\le x\le 1.

3. The function
y=\tan^(-1)x has the domain:


-\infty\le x\le \infty.

Thus, option B is true, the functions
y=\cos^(-1)x and
y=\sin^(-1)x have the same domain.
