Final answer:
The term that describes a seed vegetable that is young, tender, with firm, crisp pods is a legume (Option C). Legumes are a type of fruit known as pods, which have the seeds of the plant.
Step-by-step explanation:
The term that describes a young, tender, and firm seed vegetable with crisp pods is a 'legume'.
Legumes are a type of fruit known as pods, which contain the seeds of the plant. Examples of legumes include soybeans, peas, and beans.
When the pods are young and tender, they have a firm and crisp texture, which makes them desirable for consumption.
This is in contrast to other plant structures like tubers, which are modified stems that store starch, and bulbs, which function as underground storage units.
Hence, the correct answer is Legume (Option C).
