If the solubilities of different components (in a liquid-liquid extraction
system) increase with rise in temperature, then the temperature above
which they dissolve completely is known as the critical solution temperature
(CST or consolute temperature). If solubilities increase with decrease in
temperature, then CST is the temperature below which they dissolve
completely. If a binary system has no critical solution temperature, it
implies that
(A) The system comprises of partially miscible liquids
(B) The system comprises of miscible liquids
(C) The system comprises of an azeotrope
(D) On heating, a vapor phase will appear; while on cooling, a solid phase
will appear
