I had been asked this question by my college director while I was bunking the class.

The doubt is from Ground Techniques topic in section Site Investigation and Ground Techniques of Construction & Building Materials

Answer 1

Right answer is (b) 3000 mm^2 to 7500 mm^2

The explanation: In method of loading comma the size of square steel plate generally variance from 3000 mm^2 to 7500 mm^2. The plates should have sufficient thickness to with stand the maximum bending stresses due to probable loading. But in no case, it should be less than 25 mm.
