Please answer the attached question. Please.......... ....

Larger diameter axons have a higher conduction velocity, which means they are able to send signals faster. This is because there is less resistance facing the ion flow. We have a lot of ions flooding into the axon, so the more space they have to travel, the more likely they will be able to keep going in the right direction.

Presence of Myelin sheathe helps in faster conduction of Action potential.
so ans should be 4)
