Best answer
Correct choice is (a) Multiple effect evaporator

Easiest explanation: Considerable saving in steam and water can be effected by using multiple effect evaporators. The vapors from one effect have considerable latent heat and may thus be used for heating second effect and vapors from the second effect to heat the third effect and so on. Thus great economies of operation may be made in large installations with multiple- effect evaporator.
