The Correct Option is D
Solution and Explanation
Given $f(x)=g(x) h(x)$
$\Rightarrow h(x)=\frac{f(x)}{g(x)}$
$\Rightarrow \displaystyle\lim _{x \rightarrow 1} h(x)$
$=\displaystyle\lim _{x \rightarrow 1} \frac{f(x)}{g(x)}$
$\Rightarrow h(x)=\frac{f(x)}{g(x)}$
$\Rightarrow \displaystyle\lim _{x \rightarrow 1} h(x)$
$=\displaystyle\lim _{x \rightarrow 1} \frac{f(x)}{g(x)}$

Fundamental Theorem of Calculus
Fundamental Theorem of Calculus is the theorem which states that differentiation and integration are opposite processes (or operations) of one another.
Calculus's fundamental theorem connects the notions of differentiating and integrating functions. The first portion of the theorem - the first fundamental theorem of calculus – asserts that by integrating f with a variable bound of integration, one of the antiderivatives (also known as an indefinite integral) of a function f, say F, can be derived. This implies the occurrence of antiderivatives for continuous functions.
