Solution

The correct option is C spiral away from the positive charge and finally escape from the binding of the positive charge

Negative charge is revolving around a fixed.
The spinal away from the positive charge and finally escape from the binding of the positive charge.
Hence, the charged particle was initially stationary, uniformly for a short period of time and than - stopped accelerating.
