Concept:Legumelin is a simple plant protein found in leguminous seeds.
Proteins are classified by shape into globular and fibrous types.
Explanation:Legumelin has a compact, roughly spherical molecular shape.
It dissolves readily in water and salt solutions, which is typical of globular proteins.
It is not a carbohydrate, since it is proteinaceous in nature.
It is not an enzyme, because it does not catalyze biochemical reactions.
It is not fibrous, because fibrous proteins have long, thread-like structures with structural roles.
Due to its spherical conformation and solubility, legumelin qualifies as a globular protein.
Therefore, the correct choice is option B.
Answer:Option B — Globular protein.
