Final answer:
The correct sequence for the swing phase of gait is Toe-off, Mid-swing, and Heel-strike, which corresponds with option B.
Step-by-step explanation:
The proper sequence of the swing phase of gait is represented by option B: Toe-off, Mid-swing, Heel-strike. The swing phase starts with the toe-off, where the toes leave the ground. This is followed by the mid-swing, where the foot is moving forward through the air, and the phase ends with the heel-strike, when the heel makes contact with the ground, preparing to transition into the stance phase of the gait cycle.
