The transformation of the larvae into an adult frog is called

Options

A. metamorphosis
B. hibernation
C. fertilisation
D. qulescency

Answer

**Step-by-Step Solution:**

1. **Understanding the Lifecycle of Frogs**: The transformation of a larva into an adult frog is part of the frog's lifecycle. Frogs undergo a process known as metamorphosis, which involves several distinct stages.

2. **Identifying the Stages of Metamorphosis**: Metamorphosis in frogs consists of four main stages:
- **Egg Stage**: The lifecycle begins when a female frog lays eggs in water.
- **Tadpole Phase 1**: The eggs hatch into tadpoles, which are aquatic and have gills for breathing.
- **Tadpole Phase 2**: As tadpoles grow, they begin to develop legs and their tails start to shorten.
- **Froglet Stage**: The tadpole continues to develop, losing its tail and developing lungs, transitioning into a froglet.
- **Adult Frog**: Finally, the froglet matures into an adult frog, capable of living on land and reproducing.

3. **Conclusion**: The entire process from larva (tadpole) to adult frog is called **metamorphosis**. This term specifically refers to the transformation that occurs during the lifecycle of amphibians like frogs.

4. **Answer Selection**: Given the options provided (metamorphosis, hibernation, fertilization, quiescency), the correct answer is **metamorphosis**.
