As per the given question,

c. sin\theta=\sqrt{1+cos^2\theta} is not correct.

Its proof is given below,

___________________________________________________

As we know,

sin^2\theta+cos^2\theta=1\\or, sin^2\theta= 1-cos^2\theta\\:. sin\theta=\sqrt{1-cos^2\theta}

Thus, due to this reason, C. [ sin\theta=\sqrt{1+cos^2\theta}   ] is not correct.
