Answer»

The correct answer is (d) LOW heat cement

Easy explanation: Dam construction will involve MASS CONCRETING where heat of hydration is the major concern which if not monitored will cause CRACK in the bulk of the dam which is undesirable, hence low heat cement is preferable in this TYPE of concreting.
