Which example possesses mechanical potential energy?
a. a taut guitar string
b. an oscillating pendulum
c. a roller coaster ride
d. a child on a swing
e. a speeding car

Option A: a taut guitar string

Explanation:

The sum total of kinetic energy and potential energy is known as mechanical energy. The energy possessed by a body due to virtue of its position is known as mechanical potential energy. The energy possessed by a body due to virtue of its motion is known as motion is known as kinetic energy.

A taut guitar string possesses only mechanical potential energy.

The rest of the examples have either kinetic energy or combination of potential energy plus kinetic energy.

Hence, option A is correct.
