D15 frequencies are which of the following?

In aviation radio navigation, certain channel designations come with paired frequencies in two bands: a VHF frequency for civilian use and a UHF frequency for TACAN/DME, with the UHF value typically 200 MHz higher than the VHF. For D15, the appropriate VHF frequency is 127.0 MHz, and the matched UHF frequency is 327.0 MHz. This paired set is the one defined for D15, which is why 127.0 and 327.0 is the correct pairing. The other options don’t maintain the correct VHF/UHF pairing pattern.
