A nerve net consists of interconnected neurons lacking a brain or any form of cephalization. Unlike central nervous systems, where neurons are typically grouped together, neurons found in nerve nets are found spread apart. This nervous system allows cnidarians to respond to physical contact.

Explanation: Electrons, protons and neutrons basically make an atom.
Neutron has no charge - electrically neutral
Protron carries a positive charge

So, it is a function of electron transfer.
The answer is option B
