Concept: When a line intersects 2 parallel lines the length of the intersecting line is minimum when the intersecting angle is 90 degrees. Further when the angle keeps on decreasing the length of the intersecting line keeps on increasing.
In this case, the angle made by the segment CD is 60 degrees and the angle made by the segment AB is 61 degrees.
As per the above mentioned concept, the length of CD > length of AB, Hence, the correct option is (B)

For this problem, we told that since the 2 horizontal lines are parallel, then we can deduce that the space b/t the 2 lines would be uniform.
Meanwhiles, it is told that Line AB intesct with bottom lines at the angle of 61。 while CD cross with bottom line at 60。
It is very conspicuous the lower the degrees which a line interect with paralles, the longer the length would be.
