A) MOD 128, 128 counts, 127 maximum count, and 23,437.5 Hz
B) MOD 512, 512 counts, 511 maximum count, and 2,929.69 Hz
C) MOD 256, 256 counts, 255 maximum count, and 5,859.38 Hz
D) MOD 256, 256 counts, 255 maximum count, and 11,718.75 Hz

An eight flip-flop binary counter has a MOD number of 2^8 = 256, meaning it can count from 0 to 255, which is 256 counts in total. The maximum count is 255. The output frequency is the input frequency divided by the MOD number, so 1.5 MHz / 256 = 5,859.38 Hz.
