(a) Freeze drying

(b) Organic solvent

(c) Inorganic clays like bentonite

(d) Creating metastable polymorphs

This question was posed to me in quiz.

Answer 1

Correct option is (c) Inorganic clays like bentonite

Explanation: In the process of selective adsorption on insoluble carriers a highly active adsorbent as the inorganic clays like bentonite can enhance the dissolution rate of poorly aqueous soluble drugs such as indomethacin, it maintains the concentration gradient at its maximum.
