Question

When a pendulum is at the midpoint of its oscillation, hanging straight down, which statement is true?

Answer 1

When a pendulum is at the midpoint of its oscillation, hanging straight down ...

-- that's the fastest it's going to swing, so its kinetic energy is maximum;
and
-- that's the lowest it's going to get, so its potential energy is minimum.

'c' is your choice.

Answer 2

c. Kinetic energy is maximum and potential energy is minimum.
