(d) Low pressure drops and viscosity should be low

I have been asked this question in quiz.

Answer 1

Correct answer is (d) Low pressure drops and viscosity should be low

The best I can explain: Absorbent is defined as the material having ability to absorb another substance. Absorbents should usually be having low pressure drops in absorption tower and low viscosity for rapid absorption rates.
