which reason best explains why plasmas are good conductors of electricity?
○ they have mobile charged particles.
○ they are at extremely high temperatures.
○ they are made up of particles in fixed positions.
○ they have slow-moving nuclei that carry electricity.

Explanation:

Electrical conductivity requires mobile charged particles that can carry electric current. Plasmas consist of ionized gas with free electrons and positive ions, which are mobile charged particles, enabling them to conduct electricity well. High temperatures create plasmas but do not directly explain conductivity; fixed particles and slow-moving nuclei would not support electrical conduction.

Answer:

A. They have mobile charged particles.
