I got this question by my college director while I was bunking the class.

I need to ask this question from Analysis of Well Foundation topic in section Well Foundations of Geotechnical Engineering II

Answer 1

Correct option is (a) Active and passive states

Explanation: When a rigid soil, embedded in sand, starts moving parallel to its original position under the action of a horizontal force, it transforms the soil on one side to passive state and the other side in to active state.
