The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

4CH33C|COOC2H5=2CH1COOH

Here since COOH is the principal functional group it gets lowest number than the secondary functional group (3-carbethoxy). So it is 3-carbethoxy-2-butenoic acid
