Solution

The correct option is B F, T, T, F, F

During asexual reproduction, protozoa follow different methods such as binary fission, multiple fission, and budding.
Digestion begins in the crop, but most of the food in insects and birds is pushed through a narrow passage in the alimentary canal called the gizzard.
Birds and reptiles excrete uric acid during excretion as uric cid is less toxic and reduces water loss and the subsequent need for water.
Ichthyophis go through a metamorphosis in which aquatic larva transition into fossorial adults. Penguin is a bird that does not shows metamorphosis.
Nematocysts are explosive cells commonly found in the animals of the Phylum Cnidaria.

So, statement 1, 4 and 5 are false, rest 2 and 3 are true. Therefore, option-c is correct.
