Provide an Appropriate Response $A B C D$ , And $p(A)=10, p(B)=20$

True/False

Provide an appropriate response.
-Consider a linear program with an objective function for profit. Thinking of isoprofit lines, if the objective function is evaluated at the corner points of polygon $A B C D$ , and $p(A)=10, p(B)=20$ , and $p(C)=5$ , is it safe to assume that $p(D)$ is not the corner point at which the profit is maximized?
