$\begin{array}{cc}\text{a. Budding}& \text{i. Amoeba}\\ \text{b. Binary Fission}& \text{ii. Hydra}\\ \text{c. External fertilisation}& \text{iii. Human beings}\\ \text{d. Internal fertilisation}& \text{iv. Frog}\end{array}$

• A. a-ii, b-iv, c-i, d-iii
• B. a-ii, b-i, c-iv, d-iii
• C. a-ii, b-i, c-iii, d-iv
• D. a-ii, b-iii, c-iv, d-i

Answer 1

The correct option is B a-ii, b-i, c-iv, d-iii

• Hydra reproduces by budding. Here the parent produces a small bud that gradually grows in size and then separates from the parent body.
• Amoeba reproduces by binary fission. Here the parent body divides into two equal and similar halves. Each half forms a new individual.
• The process of fertilisation that occurs outside an organism's body is called external fertilisation. Frog reproduces by external fertilisation.
• Internal fertilisation takes place inside the body of an individual. It is necessary for the sperm to reach inside the female's body (to ovum) for fertilisation to occur. Internal fertilisation occurs in various organisms like hens, cows, dogs, humans, etc.
