Vedclass · Answer

(D) The correct statement is $(d)$. By the fundamental theorem of calculus,if a function $f(x)$ is differentiable at a point $x = c$,then it must be continuous at that point $x = c$. However,the converse is not necessarily true; a continuous function may not be differentiable (e.g.,$f(x) = |x|$ at $x = 0$). Therefore,$(d)$ is the only universally true statement among the given options.
