What is required more when swerving in a curve compared to swerving in a straight line?

Answer: C — Traction

When swerving in a curve, traction is the most important factor because the tires need to maintain grip on the road to make the turn without losing control. Braking power will also be important in order to slow down the vehicle before entering the curve, but it is not the most crucial factor. Balance and acceleration are not as crucial in swerving in a curve compared to swerving in a straight line.
