ALeaf spring suspension will bottom out, reducing steering response
BThe differential automatically transfers torque, causing oversteer
CThe camber reduces effective tyre contact area, increasing rollover risk
DAir suspension height sensors may trigger an emergency stop

✓ Correct answer: C. The camber reduces effective tyre contact area, increasing rollover risk A high-sided PCV has a high centre of gravity; when nearside wheels drop into a road dip, the vehicle's effective lean angle increases and the stability margin against rollover is significantly reduced — drivers must maintain appropriate speed and smooth steering.
