Suppose that a clock is carefully calibrated to tick at a regular rate. If one is brought inside a strong gravitational field, an observer far from that gravitational field would measure the clock to tick
A) at the same rate in a gravitational field if it is an atomic clock but at a slower rate if it is a mechanical clock.
B) at the same rate, wherever it is placed in a gravitational field.
C) slower the closer it comes to the source of gravity.
D) faster the closer it comes to the source of gravity.

According to the theory of general relativity, time dilation occurs in a strong gravitational field. This means that a clock closer to a massive object (and thus in a stronger gravitational field) will tick slower compared to a clock further away from the source of gravity, as observed from a distance. This effect is independent of the clock's mechanism, affecting both atomic and mechanical clocks.
