Answer: A) 2/3
Method: Here’s an easy method for questions like these, when you are looking at a triangle, look at the angle that’s away from the biggest line (if it’s a right triangle choose any angle), for this case angle W. Now count how many lines it takes to get to the big line, for the original triangle it’s 6 and for the new triangle it’s 4. Now since you have your numbers turn it into a fraction (new on top original on bottom), 4/6. Finally see what the answer is, for this case 4/6 is equal to 2/3, so there’s your answer.
