Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

option D it is two components system So two phases form. On increase in volume of water first phase ( i.e water in phenol) decreases and second phase ( i.e phenol in water) increases. Here component 2, phase 2, so degrees of freedom (F)=2-2+2=2 i.e Bivariant . In this experiment if pressure remain constant then, F=2-2+1=1 i.e univarient system.
