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 (D) Fold hinge Cleavages are generally parallel to the axial plane of any fold. The angle between the cleavage and bedding should be Highest (around 90°) in the hinge zone. As you will move away from the hinge zone, the angle between bedding and cleavage will decrease continuously. See the attached figure for details.

At the hinge zone the the axial plane and limb has angle like 90 degree so it will be maximum.
sir in question as they are talking about cleavage. is it that cleavage that is formed by compression?.
then we are comparing with other bedding
yes it's that one. axial plane and cleave are parallel so we call them as axial planar cleavage
