The part which we eat in Mango is:

Correct answer: (b) Mesocarp

Explanation

A mango is a drupe, whose fruit wall (pericarp) has three layers: epicarp, mesocarp and endocarp.

The mesocarp is the thick, fleshy, juicy middle layer that we actually eat.

The epicarp is the outer skin and the endocarp is the hard stony layer around the seed, so neither is eaten.
