Nervous tissue is not found in (c) tendons.
Explanation: Nervous tissue is composed of neurons and glial cells, which are found in the brain, spinal cord, and nerves. Tendons, on the other hand, are a type of connective tissue that connects muscles to bones and does not contain nervous tissue.
Why other options are incorrect:
(a) brain:
The brain is the primary organ of the central nervous system and is made up of nervous tissue.
(b) spinal cord:
The spinal cord is also part of the central nervous system and is composed of nervous tissue.
(d) nerves:
Nerves are bundles of axons (nerve fibers) that extend from the brain and spinal cord. These nerves are also considered part of the nervous system.
