Concept:
This question tests verbal analogies based on biological relationships, specifically the relationship between an adult animal species and its corresponding offspring or larval stage.
• First Pair Analysis: A Lamb is the recognized term for a young, juvenile offspring of a Sheep.
• To establish the matching analog pair, we must identify the precise term used to denote the juvenile or larval developmental offspring stage of a Frog.
Step 1: Identifying the biological offspring terms for all choices.
Let's analyze what each option means contextually to find the correct fit:
• Option (A) Calf: This is the biological term for the young offspring of cattle (cows, bulls) or large mammals like elephants and whales.
• Option (B) Tadpole: This is the specific aquatic larval stage of an amphibian, specifically a frog or toad, which undergoes metamorphosis to become an adult.
• Option (C) Kits: This is the young offspring of certain small mammals such as foxes, ferrets, or rabbits.
• Option (D) Cub: This represents the juvenile offspring of carnivorous mammals such as lions, bears, tigers, and wolves.
Step 2: Conclusion.
Since a young frog is scientifically and commonly termed a tadpole, the logical analog relationship is structured as:
\[
\text{Sheep} : \text{Lamb} :: \text{Frog} : Tadpole
\]
This perfectly corresponds to Option (B).
