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.

This one seems to be confusing. But if I have to go for the best option that is compatible with the given question, then it would be time. Because if we consider Metamorphism and metasomatism both then they nvolve the reequilibration of mineral assemblages due to changes in pressure, temperature and ⁄ or chemical environment. Time acts as a catalyst in this case of metamorphism which may increase the rate of metamorphism with time if all the conditions remain intact and followed perfectly. So correct option - 4 (geologic time)
