A. Epithelial B. Muscle C. Connective D. Nervous

______ tissue can be found in the brain, spinal cord, and nerves. A.

D. Nervous

The correct answer is D. Nervous tissue.

To arrive at the correct answer, we need to understand the characteristics of different types of tissues and the specific locations where they are found.

A. Epithelial tissue: This type of tissue covers the surfaces of organs, lines body cavities, and forms glandular tissue. It can be found in the skin, lining of the digestive system, and respiratory tract.

B. Muscle tissue: Muscle tissue allows for the movement of body parts and organs. There are three types of muscle tissue: skeletal, cardiac, and smooth. Skeletal muscle is attached to bones and allows for voluntary movement, cardiac muscle is found in the heart, and smooth muscle is found in the walls of organs such as the stomach and blood vessels.

C. Connective tissue: Connective tissue provides support, protection, and framework for the body. It includes different types such as bone, cartilage, blood, and adipose tissue (fat). Connective tissue can be found in various parts of the body, including bones, tendons, ligaments, and blood vessels.

D. Nervous tissue: This type of tissue is responsible for transmitting and processing information in the body. It consists of nerve cells called neurons, which are specialized to receive, generate, and transmit electrical signals, and neuroglia cells, which support and protect the neurons. Nervous tissue can be found in the brain, spinal cord, and nerves.

Therefore, based on the description provided, the correct answer is D. Nervous tissue.
