The correct answer is B: Additional lobes form with major lobes increasingly aligned with the axis of the antenna. As the wire length of an unterminated long wire antenna is increased, additional lobes form with major lobes increasingly aligned with the axis of the antenna. Longer wires create more lobes, and the main lobes point more along the wire direction. Long wire antennas create multiple lobes as length increases. With a 1-wavelength wire, you might have 2 main lobes. As you go to 2 wavelengths, 3 wavelengths, etc., more lobes appear. The major lobes tend to align more with the wire axis as length increases. This is why very long wires (several wavelengths) have their strongest radiation along the wire direction. The pattern becomes more complex with more lobes, but the main radiation is increasingly end-fire (along the wire).
