The foundations are placed below ground level, to increase A. strength B. workability C. stability of structure D. all the above.

The foundtions are basically to divide the loads of a structure to the soil.n So A, yes, for B workability, not always, sometimes the foundation is integrated in the groundfloor. What is workability? putting foundations in the ground can be difficult. C: yes , also to divide the forces for the shear stability to the soil.

Totally agreed with the answer of eng. Wolf

For each type of soil there was suitable foundation , but the main function of the foundations is distributing loads of the structures inside strength layers of the soil owing to keep the structures more stable ,strength and durable 

C. stability of structure.

Option "C" Stability of Structure

I guess  C.Stability and A.Strentgh 

Option C

c

I think the correct answer is C 

Option C
