Vedclass · Answer

(C) $Calotropis$ (Aak) is a plant that produces highly poisonous cardiac glycosides,which prevent cattle and goats from grazing on it. Thus,the Assertion $(A)$ is correct.However,$Calotropis$ does not possess thorns; it relies on chemical defense mechanisms (toxins). Thorns are indeed a morphological means of defense in plants (such as in $Acacia$ or $Cactus$),but this does not apply to $Calotropis$. Therefore,the Reason $(R)$ is incorrect.
