D: ff
Step-by-step explanation:
You basically look at the box it's asking for, let's use A as an example. On the top where the A column is there's F, so that's one of the thingys I forgot what they're called. Next look at the row of A, and there's f. Put the 2 together and you get Ff. Reminder that any uppercase ones come first.
