Best answer
The correct option is (a) Agrobacterium tumifaciens

The explanation is: Agrobacterium tumifaciens is the bacteria which transfers ‘T-DNA’ within plants. It mostly infects dicot plants. This ‘T-DNA’ is responsible for the formation of transformed cells called tumors from normal plant cells.
