Solution

The correct option is B A-Penumbra, B-Umbra

Umbra- This portion of shadow is completely dark as no light reaches from the source of light due to the opaque object.
Penumbra- This portion of shadow is not completely dark as only a small portion of source of light is covered by the opaque object.
The lighter part of shadow which forms at a larger distance from the object is called antumbra.
