Solution and Explanation
Concept:
Morphological defence means structural modification of plant parts for protection against grazing animals and other harmful factors.
Step 1: Observe Acacia and cactus.
Acacia and cactus commonly possess sharp thorn-like structures. \[ \text{Acacia and cactus} \rightarrow \text{Thorns} \]
Step 2: Function of thorns.
Thorns protect plants from herbivores and reduce damage. \[ \text{Thorns} \rightarrow \text{defence} \]
Step 3: Final answer.
Thus, the most common morphological defence in Acacia and cactus is thorns. \[ \therefore \text{Correct Answer is (C)} \]
