I'm 100% sure it can't be C, or D

How though.. the middle section isn't a triangle.

Sometimes, it's easier to understand it when you separate the triangles. Notice that every triangle has a right angle and angle 1. By AA Similarity, all three triangles are similar.

Alright, I see, I thought you actualy had to see the triangle, not seperate it

Why was B not the answer? Look at the middle triangle. It is equilateral (all sides congruent measuring 10). An equilateral triannlge is also equiangular with all angles measuring 60. One other triangle has two 50-deg angles, and the other triangle has two 49-deg angles, so there is no AA Similarity here.

Because the third triangle in B has 49 degree angles not 50 like the first triangle. Making them not similar

There is no need to separate the triangles. If you notice they are similar without separating, that's fine. Separating them is only a help.
