B Correct answer
Explanation

In upcut milling (conventional milling), the workpiece is fed against the rotation of the cutter. This means the cutter teeth engage the material at the thickest part first. This is opposite to downcut (climb) milling where feed is in the same direction as cutter rotation. The direction affects tool life and surface finish.
