B. 12 in., 6 in., 3 in.
C. 12 in., 12 in., 12 in.
D. 12 in., 8 in., 4 in.

Answer 1

the easiest way to do these type questions is pick out the biggest number, and check that the other two add up to something bigger than it.

Answer 2

for example, choice A: 48 is biggest. add up the other two 12+24= 36
36 is not bigger than 48, so this can't be a triangle.
