The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Plants, Unlike animals have no specialized organs for gaseous exchange gaseous exchange in plants occurs by diffusion through stomata and lenticels. There are various reason for the absence of respiratory organs in plants. Each part of plant takes care of its own gas exchange needs. There is little transport of gases from one part to another. Plant do not require much demands for gas exchange. Thus the distance that gases must diffuse is not large.
So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
