Which option is NOT one of the four tissue types found in the human body?

• A. Epithelial
• B. Connective
• C. Endocrine
• D. Nervous

Answer: (C)

The basic tissue categories in the body are epithelial, connective, muscle, and nervous tissue. Endocrine isn’t a tissue type; it’s a system made up of glands and organs that secrete hormones. Glands like the thyroid or adrenal are composed of epithelial tissue, but “endocrine” itself isn’t a distinct tissue category. So the option that isn’t one of the four tissue types is Endocrine. The other choices are actual tissue types with clear roles: epithelial forms coverings and glands, connective provides support and transport, and nervous tissue transmits signals.
