D Correct answer
Explanation

Drilling is an oblique cutting process because the drill's cutting edges are inclined to the direction of feed motion, not perpendicular to it. Unlike orthogonal cutting where the cutting edge is perpendicular to the feed direction, drilling involves the cutting edge working at an angle, with the drill point geometry creating complex cutting action where the edge is not at 90° to the feed direction.
