Why and is 2 and not 4 please explain me in detail.Thank you

Hello shaily,
See the option 4 is hydra which undergoes asexal reproduction but will not produce any vegetative propogule but it only undergoes budding through asexual reproduction but you see all the three i,e ginger through rhizome and BRYOPHYLLUM THROUGH ADVENTITIOUS BUDS AND OFFSET are all vegetative propogules
