General — Hard JEE math MCQ
Let the functions $f: \mathbb{R} \rightarrow \mathbb{R}$ and $g: \mathbb{R} \rightarrow \mathbb{R}$ be defined by
\[
f(x)=e^{x-1}-e^{-|x-1|} \quad \text { and } \quad g(x)=\frac{1}{2}\left(e^{x-1}+e^{1-x}\right)
\]
Then the area of the region in the first quadrant bounded by the curves $y=f(x), y=g(x)$ and $x=0$ is
- A. $(2-\sqrt{3})+\frac{1}{2}\left(e-e^{-1}\right)$
- B. $(2+\sqrt{3})+\frac{1}{2}\left(e-e^{-1}\right)$
- C. $(2-\sqrt{3})+\frac{1}{2}\left(e+e^{-1}\right)$
- D. $(2+\sqrt{3})+\frac{1}{2}\left(e+e^{-1}\right)$
