The displacement (s) of an object accelerating from rest can be calculated using the formula $s = \frac{1}{2}at^2$, where $a$ is the acceleration and $t$ is the time. Rearranging for $a$, we get $a = \frac{2s}{t^2}$. Substituting $s = 25$ m and $t = 12$ s, we find $a = \frac{2 \times 25}{12^2} = \frac{50}{144} = 0.347$ m/s$^2$, which rounds to $0.35$ m/s$^2$, making option B correct.
