What is the velocity factor of a transmission line?

Direct answer summary (2024-2028 NCVEC pool)

The official correct answer for E9F01 is The velocity of a wave in the transmission line divided by the velocity of light in a vacuum.

The key fact is The velocity of a wave in the transmission line divided by the velocity of light in a vacuum. Match that fact to the exact condition in the question; the other choices describe a different rule, band, component, or operating situation.
