The displays that could be represented by a single bit are:

(Choice C) The temperature unit indicator ("C" or "F") - This can be represented with 1 bit since there are only two options (C or F).

(Choice F) The "PM"/"AM" indicator - This can also be represented with 1 bit since there are two options (PM or AM).

Thus, the correct answers are C and F.
