SOMEONE PLEASE PLEASE HELP

A swinging simple pendulum is an example of conservation of energy : ... When the bob reaches the centre position A, it has only kinetic energy (but no potential energy). As the bob goes from position A towards position C, its kinetic energy goes on decreasing but its potential energy goes on increasing.

what are the options.

explanation:

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.
