ASSERTION REASON
Assertion:
Assertion (A): Let $f(x) = e^{x}$ and $g(x) = \log x$. Then $(f + g)x = e^{x} + \log x$ where domain of $(f + g)$ is $\mathbb{R}$.
Reason:
Reason (R): $\text{Dom}(f + g) = \text{Dom}(f) \cap \text{Dom}(g)$.
(A)
Both A and R are true and R is the correct explanation of A.
(B)
Both A and R are true but R is NOT the correct explanation of A.
(C)
A is true but R is false.
(D)
