The answer is B.
When air is being pumped into a tire, it increases the potential energy because the bike can go further with more air.
The further the weight is lifted off the ground, the more potential energy it has (the more distance it can fall).
The further a roller coaster goes uphill, the energy it is storing for the trip downhill.
When a spring is stretched, it stores more and more energy until it is completely taut, and until it is let go of.
