Practice question

Go with C — Fetal and early childhood. Within Endocrinology, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, cause and effect line up with Fetal and early childhood — that is the mechanism or reason the stem is pointing to. Holding that picture in mind makes Fetal and early childhood feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Fetal and early childhood.
