A supernova is primarily caused by processes related to the **force of gravity** (option b) acting on a star's core. There are two main types of supernovae:
1. **Type I Supernovae**: These occur in binary systems where a white dwarf accumulates matter from a companion star until it reaches a critical mass, leading to a thermonuclear explosion.
2. **Type II Supernovae**: These happen when a massive star exhausts its nuclear fuel, causing the core to collapse under gravity. The outer layers then rebound and explode outward.
Therefore, the most relevant answer is **b. force of gravity**.
