Perpendicular parking is entered by which sequence of actions?

Answer: B — Enter the space by maintaining distance, aligning the front bumper, and centering the vehicle.

Entering a perpendicular parking space safely means lining up and guiding the vehicle straight into the space. You approach with enough distance from other parked cars, bring the front bumper in line with the opening of the space, and then steer to center the vehicle inside. This keeps you clear of adjacent vehicles and the curb, makes it easy to exit later, and helps you judge the space width as you go in. Other approaches that start at an angle without regard to distance can lead to misalignment or contact with nearby cars or curbs, so the straight, centered entry is the correct method.
