Question

Accepted Answer

Explanation:

1. **Justification for Option 1 (Poisonous Snake):**
   - Afai, Krait, and Duboiya are indeed species of poisonous snakes. These snakes are known for their venomous nature, which they use for hunting prey and self-defense. 
   - The Krait, for example, is a well-known venomous snake found in South and Southeast Asia. It is highly dangerous due to its potent neurotoxic venom.
   - Duboiya, commonly known as the Russell's Viper, is another highly venomous snake found in Asia. It is responsible for a significant number of snakebite incidents in its range.
   - The term "Afai" might be less commonly known, but it is important to note that the context of the question groups it with other well-known venomous snakes, reinforcing the classification as a poisonous snake.

2. **Explanation for why other options are incorrect:**
   - **Option 2 (Fish):** Afai, Krait, and Duboiya are not species of fish. Fish are aquatic animals with gills, fins, and scales, which are entirely different from the characteristics of snakes. These names are specifically associated with snakes, not fish.
   - **Option 3 (Nonpoisonous Snake):** The species mentioned are known for their venomous nature. Nonpoisonous snakes do not possess venom that can harm humans or large prey, whereas Afai, Krait, and Duboiya are recognized for their dangerous venom.
   - **Option 4 (Frog):** Frogs are amphibians, which are distinct from reptiles like snakes. They have different biological and ecological characteristics. The names Afai, Krait, and Duboiya are not associated with any frog species.

In conclusion, Option 1 is the correct answer because Afai, Krait, and Duboiya are all species of poisonous snakes, known for their venomous capabilities. The other options do not accurately describe these species.
