D) a poison produced by an organism

The correct answer is B) a poison produced by an organism.

To arrive at this answer, it is beneficial to understand the different meanings of the word "secrete" and eliminate the incorrect options.

A) To produce and give off a substance: While the word "secrete" can refer to the act of producing and giving off a substance, this definition does not align with the specific meaning of "secrete" in this context.

C) A juvenile form of an animal: This definition does not match the meaning of the word "secrete" in any sense.

D) A worm-like amphibian that burrows in the soil: This definition does not correspond to the meaning of "secrete." The word you may be referring to is "segmented" rather than "secrete."

E) A change in physical form and structure due to maturity: This definition does not accurately define "secrete" either. The word commonly associated with this definition is "metamorphosis," not "secrete."

By process of elimination, we are left with option B) - "a poison produced by an organism" - as the correct definition of "secrete" in this context.
