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.

Answer: Option-C is correct because high point of the hinge line in a doubly plunging fold is called as culmination and low point is called as depression. Option-A is wrong because interlimb angle is measured in profile plane (not in cross section). In Option-A, cross section is mentioned which makes it wrong. Profile plane is the plane perpendicular to the fold axis.
