Under what condition is the instantaneous acceleration of a moving body equal to its average acceleration over time?

A. only at positive accelerations

B. only at negative accelerations

C. only at zero acceleration

D. only at constant accelerations

**I thought both C and D applied, but I can only choose one... Not sure, what do y'all think? Thanks! @perl
