While practicing S-turns, a consistently smaller half-circle is made on one side of the road than on the other, and this turn is not completed before crossing the road or reference line. This would most likely occur in turn:

A) 1-2-3 because the bank is decreased too rapidly during the latter part of the turn.

B) 4-5-6 because the bank is increased too slowly during the latter part of the turn.

C) 4-5-6 because the bank is increased too rapidly during the early part of the turn.
