For

x \in R, f(x)=|\log _{10} 2-\sin x \mid

and

{g}({x})={f}({f}({x}))

, then:

View answer and explanation

Correct option: C

g^{\prime}(0)=\cos \left(\log _{10} 2\right)

Option C (

g^{\prime}(0)=\cos (\log _{10} 2)

) is correct because by applying the chain rule and evaluating the derivative of the composite function g(x) at x=0, we arrive at this result.
