Solution

The correct option is D Both A and B
The tobacco plant was genetically modified by introducing a gene to produce antibodies. The plant was introduced with the gene for producing antibodies against the rabies virus which are similar to the antibodies produced in the humans. The antibodies from the plant can be purified and used as injections or vaccines. These vaccines help in providing immunity against the rabies virus.
The tobacco plants can also be modified to survive under the conditions of stress. The plants can bear extreme conditions like water stress, salinity and heat stress.
