Option “A” is the correct one i.e., heat flowing along X-direction.
• In rectilinear, the heat flows laterally a straight path i.e, along X- direction.
• The word rectilinear states to motion in a straight path that is along one direction.
• In this motion, the line always kept straight, and the direction of velocity remains the same.
