A. False. We can't use SSS as we don't know anything about the third pair of sides (the outer pair furthest way from each other)
B. True, we use SAS. We know info about two pairs of sides along with the pair of angles between those sides. It's not visually given, but we use the vertical angle theorem to show that the angles are congruent.
C. False. We only have info about one pair of angles and not two pairs of angles
D. False. This can be ruled out since A has been ruled out.
You have the correct answer.
