(c) Chisel plough

(d) Rotavator

I have been asked this question by my school principal while I was bunking the class.

This intriguing question comes from Tillage System in chapter Tillage, Disc Plough & Numericals of Farm Machinery

Answer 1

Correct choice is (a) Turn Wrest plough

The explanation: Turn Wrest plough, while moving in one direction the plough throws the soil in one direction and at the return trip the direction of the plough is changed, thus the plough starts throwing the soil in the same direction as before.
