I got this question by my college professor while I was bunking the class.

This key question is from Hot Rolling in section Forming Process of Casting-Forming-Welding II

Answer 1

The correct option is (c) Clockwise-anticlockwise- clockwise

For explanation I would say: In three high rolling mill, the direction of the rollers in the top and bottom are the same, and the direction of the roller in the middle is opposite to the two.
