Step 1: Understanding walk cycle motion.
A walk cycle is the sequence of frames showing how a character’s legs and body move during a step. The midpoint represents the passing position, where one leg passes the other while the body is balanced.
Step 2: Explanation.
In the given set of options, Option B correctly depicts the mid-position with one leg lifted and crossing the other while the arms are in opposite swing motion, maintaining balance.
Step 3: Conclusion.
Thus, Option B correctly completes the walk cycle.
