B) 2L
C) L/2
D) 0.707 L
E) 1.414 L

The lowest possible frequency, also known as the fundamental frequency, corresponds to a standing wave where the string vibrates in one segment with two nodes at the ends and an antinode in the middle. This setup has a wavelength of 2L, where L is the length of the string.
