Ferric chloride is the right answer.
Alum is widely used for water treatment for supply however it is not that much efficient as ferric chloride but ferric chloride cause corrosion problem in supply pipes that's why it is not prefered for water supply.
In sewage treatment, the pipes are RCC pipes hence no problem of corrosion arise and it is preferred for sewage treatment.

Both B & C are correct. Ferric Alum is generally used for treating Sewage whereas Alum is used for treating water.

Alum only for drinking water not to sewage, in sewage we should use chlorinated compound so fecl2 is the best coagulant.
