C Correct answer
Explanation

Acceleration errors in magnetic compasses are maximum on East and West headings due to the combination of magnetic dip and inertia forces. When accelerating eastward, the magnetic compass card is tilted forward by magnetic dip, then displaced backward by inertia, causing erroneous heading indications. The error is most pronounced on east/west headings because dip and inertia forces align to create maximum displacement.
