BARSIC [14]

<h2>Answer is option "D"</h2>

Explanation:

Ants rummage to discover nourishment and take it back to the state. On the off chance that they go over nourishment things that are excessively huge or substantial for a solitary individual to convey, a few species can frame groups to agreeably convey these things to the home. This aggregate route process relies on the navigational capacities of the individual ants.
