Correct option is A
The correct answer is:(A) Roots
Explanation:
The grubs of Holotrichia consanguinea, commonly known as white grubs, feed on the roots of groundnut plants.
These pests remain in the soil and damage the plant by cutting off the roots, which leads to wilting, poor nutrient uptake, and reduced yield.
Severe infestations can cause the plants to wither and die prematurely.
