False
|
|
|
Either A or B

|
None of the above

Explanation:
Detailed explanation-1: -The diameter of nerve fibre is axon, neurilemma, and myelin sheath in myelinated axons while axon and neurilemma in unmyelinated fibre. Conduction velocity is high in myelinated nerve fibre with the greater diameter. So, the given statement is false.
Detailed explanation-2: -An axon with a large diameter transmits an impulse faster than an axon with a smaller diameter. This is due to the fact that the larger diameter means more ions in an impulse can fit through the axon without having to squeeze past each other and therefore the ions don’t slow down.
