Answer is option (B), because 1st Step - we cannot count the first figure triangles because these are mentioned under the (curved) or (circle) shaped. 2nd Step - In the second figure , there are 4 triangles which we can count as it is not like as metioned as first figure..... 3rd Step - In the third figure we can only see 3 triangles but then also you guys tought that answer is d but this is not the correct way! because can you all se the 2 triangles? Ok and the triangle in which the 2 triangles are mentioned is the large triangle and the correct sum is 4 4 = 8 triangles. Hence the answer is option (B). Girls are best than boys "O"!!
