If it doesn’t contain any of the following definition then it’s wrong
A planet is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.
Both A and D work, considering that pent up stress causes all sorts of negative emotions, it really works for either one. I really wouldn't know which one to choose! If you absolutely had to, then A, because not everyone has a tendency to strike others. It does increase the probability of it happening.
