The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion**: The assertion states that "Silver fish shows complete metamorphosis." We need to determine if this statement is true or false. 2. **Defining Complete Metamorphosis**: Complete metamorphosis is a developmental process that includes four distinct stages: Egg, Larva, Pupa, and Adult. Organisms that undergo complete metamorphosis include insects like butterflies and beetles. 3. **Analyzing Silver Fish**: Silver fish (Lepisma saccharina) do not undergo complete metamorphosis. Instead, they exhibit a type of development known as "ametabolous" or "incomplete metamorphosis," where they develop through stages that do not include a pupal stage. 4. **Understanding the Reason**: The reason provided states that "In the life history of silver fish, there are four stages: Egg to Larva to Pupa to Adult." This statement is also false because silver fish do not have a pupal stage in their life cycle. 5. **Conclusion**: Since both the assertion and the reason are false, we can conclude that the correct answer is that both the assertion and reason are false. ### Final Answer: Both assertion and reason are false.
