What do we mean by gravitational time dilation?
A) It is the idea that time runs slower in places where gravity is stronger. B) It is the idea that clocks run slow for people moving at high speed past you. C) It is the idea that everyone measures time differently, depending on his/her reference frame. D) It is the idea that clocks run faster in stronger gravitational fields.

Gravitational time dilation is a form of time dilation, an actual difference of elapsed time between two events as measured by observers situated at varying distances from a gravitating mass. ... Demonstrating larger effects would require greater distances from the Earth or a larger gravitational source.
