What is the radiation pattern of a dipole antenna in free space in a plane containing the conductor?

Direct answer summary (2023-2027 NCVEC pool)

The official correct answer for G9B04 is It is a figure-eight at right angles to the antenna.

The key fact is It is a figure-eight at right angles to the antenna. Match that fact to the exact condition in the question; the other choices describe a different rule, band, component, or operating situation.
