The answer is B because the cement manufacturing process basically take 3 materials
1. Calcareous
2. Argillaceous
3. Gypsum.
The Limestone and Clay mentioned in Option A is correct but they are only 2 of the materials used for production. Marl, Chalk can also be used as other sources other than limestone. This is the reason it is Option B.
Most important part is Calcareous materials are those which contain lime and not limestone.
