Solution
The correct option is C I, III and IV
Amoeba reproduces asexually by the method of binary fission, however during unfavourable conditions it can reproduce by the method of multiple fission or sporulation.
The lifespan of a parrot is 140 years while 15 years is the
lifespan of a crow.
The phenomenon of encystation is seen in Amoeba during unfavourable conditions, it withdraws its pseudopodia and secretes hard covering or cyst around itself. It is not observed in Paramecium.
In Bryophyllum, vegetative propagation occurs by adventitious buds which arise from the notches present at the margins of its leaves.
