There are three options which are correct but one is more severe than others.
Cohesive soil- foundation construction is not a big deal.
Bearing capacity low- pile foundation is suitable.
But if volume is changing rapidly, then the behaviour of soil is very uncertain and severe than others. So in my judgement option D is correct.
