On an absolutely rigid foundation base, the pressure will A. Be more at the edges of the foundation B. Be uniform C. Not be uniform D. Be zero at the centre of the foundation

The correct answer is: C. Not be uniform.

The pressure on an absolutely rigid foundation base will not be uniform. This is because the soil below the foundation will deform under the load, and the deformation will be greater at the edges of the foundation than at the center. This means that the pressure will be greater at the edges of the foundation than at the center.

Option A is incorrect because the pressure will not be more at the edges of the foundation. Option B is incorrect because the pressure will not be uniform. Option D is incorrect because the pressure will not be zero at the center of the foundation.
