Which of the following best describes the conditions that must be met for x=c to be a point of inflection for a twice-differentiable function h on an open interval?
(a) h′′(c)=0 and h is continuous at x=c.
(b) h′(c)=0 and h′′ changes sign at x=c.
(c) h′′ changes sign at x=c, and h is continuous at x=c.
(d) h′′ changes sign at x=c but continuity of h at x=c is not required.
