(B) A11
According to the question,
A line segment AB in the ratio 4:7
So, A:B = 4:7
Now,
Draw a ray AX making an acute angle BAX
Minimum number of points located at equal distances on the ray,
AX = A+B = 4+7= 11
A1, A2, A3, ………. are located at equal distances on the ray AX.
Point B is joined to the last point is A11.
