To arrive at this answer, we can use a process of elimination by analyzing the options one by one.

A) A nodule is not specifically a type of plant, so we can eliminate this option.

B) While the term "nodule" can be used in a general sense to indicate replacement, it would not be the most common or specific definition for this term. Therefore, we can eliminate this option.

C) The term "nodule" does not refer to a chemical formed by nitrogen and another element, so we can eliminate this option.

D) While the term "nodule" can be used to describe complex chemicals in the body of organisms that serve a specific purpose, this is not the most common or specific definition for this term. Therefore, we can eliminate this option.

E) A nodule is indeed a small swelling on the root of a legume plant. This is the most accurate and specific definition for this term, so it is the correct answer.

By analyzing the options and eliminating the incorrect ones, we determined option E to be the answer.
