Two coherent radio transmitters broadcast out of phase signals with the same wavelength. A radio antenna receives a constructive interference signal from these transmitters, and is located 1.85 km away from one transmitter, and 2.25 km away from the other transmitter. The longest possible wavelength of the transmitters is:
A. 0.20 km.
B. 0.27 km.
C. 0.40 km.
D. 0.80 km.
