How does special relativity differs from general relativity?

• Special relativity applies only to moving frames while general relativity applies only to stationary frames.

• Special relativity applies only to stationary frames while general relativity applies only to accelerating frames.

• Special relativity applies only to stationary or moving frames while general relativity applies only to accelerating frames.

• Special relativity applies only to accelerating frames while general relativity applies only to stationary or moving frames.
