Answer:
Option (B).
Explanation:
Neurons or nerve cell are the basic structural and functional unit of the nervous system. Fibers are the thread like long projection of the nerve cells.
Neurons are classified into three fibers- Group A fibers, B fibers and C fibers. The group C fibers cannot capable of doing the saltatory conduction of the nerve impulse because they are unmyelinated.
Thus, the correct answer is option (B).
The stimuli alter the activity of excitable sensory cells via Transduction.
Transduction is the method by which a virus transmit genetic material from one bacterium to another.
<h3>What is Transduction?</h3>
Transduction is defined as the genetic transfer from a donor cell to another recipient by a bacteriophage. The transduction consists of two stages:
-The formation of the transducer phage particle, the genetic material is introduced inside the capsid of a phage.

A person who has cerebrospinal fluid draining from the ear probably has a fracture of the temporal bone.
<h3>What is Cerebrospinal Fluid?</h3>
All animals have cerebrospinal fluid (CSF), a transparent, colorless bodily fluid that is present in the tissue that covers their brains and spinal cords.
Specialized ependymal cells in the choroid plexus of the brain's ventricles create CSF, which is then absorbed in arachnoid granulations. About 125 mL of CSF are present at any given moment, and 500 mL are produced daily. The CSF protects the brain inside the skull mechanically and immunologically by acting as a shock absorber, cushion, or buffer. The cerebral autoregulation of cerebral blood flow is another essential role played by CSF.
The ventricular system and subarachnoid space, which are located surrounding and inside the brain and spinal cord, respectively, are occupied by CSF.
