Answers:
As shown in figure check the connecting legs, as shown A-C and B-D are short so you can one can connect one wire for switch either to A or C and other wire to B or D so when the switch is pressed the circuit is complete.

A vs B specifically? Electrically, it doesn't matter which of the pair you call A or C (or B or D) because they are tied together. You can use either pin in the pair for your circuit. What matters is pairing left side to right side when pressed.
