Mamba, krait, and viper are names encountered in zoology. They are correctly classified as:

Introduction / Context:
Taxonomic analogies ask you to recognize organisms by common names and map them to the correct biological class. Mamba (notably the black mamba), krait (e.g., common krait), and viper (family Viperidae) are all snakes, many of which are venomous and medically significant in different regions.

Given Data / Assumptions:

• Mamba → genus Dendroaspis (elapids).
• Krait → genus Bungarus (elapids).
• Viper → any member of family Viperidae.

Concept / Approach:
Match the common names to the correct high-level category “snakes” (order Squamata, suborder Serpentes). The distractors are intentionally far from zoology or mislead toward other animals.

Step-by-Step Solution:

Verification / Alternative check:
All three appear in standard lists of venomous snakes; none are product brands in this context nor supernatural entities.

Why Other Options Are Wrong:

• Insects / marine fishes / spirits / polishes: Not zoologically accurate for these names.

Common Pitfalls:
Confusing “viper” with generic “venom” or treating “mamba” as a brand; context here is zoological classification.

Final Answer:
These are snakes
