What statement best compares potential and kinetic energy

if the choices are:

A. Objects always have more potential energy than kinetic energy.

B. Only kinetic energy increases when the velocity of an object increases.  

C. Only potential energy decreases when an object’s height increases.

D. Objects always have more kinetic energy than potential energy.

then the ans is B. Only kinetic energy increases when the velocity of an object increases.  

i just learnt this recently but i need to look through my notes again

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
