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.

Garnet and coesite a great combination of ultra high pressure Sapphirine can also be added but in granulite facies it's mostly temperature dominant we consider ...and simple quartz is given so I choose the high pressure variety coesite. Spinel–sapphirine–quartz bearing composite inclusion within garnet from an ultrahigh-temperature pelitic granulite: Implications for metamorphic history and P–T path

Pyrope+Coesite is indicator of ultra high pressure metamorphism. Coesite is very high pressure polymorph of silica that's why it occurs in high pressure condition.
In case of ultra high temperature (UHT) metamorphism you will get sapphirine+Quartz assemblage but in question you have asked about ultra high pressure (UHP) metamorphism. That's why Coesite+pyrope should be answer.
ok sir thank you.
