It’s D (#m\s^2#)

To find an acceleration we take a change in velocity and divide it by time, so acceleration must have units of velocity per unit time.

Velocity is defined as a change in distance divided by a change in time, so it will have units of distance per unit time.

Thus acceleration has units of m/s #div# s = #m/s^2# or #ms^-2#

OK with that?
