In Q11 According to the solution video, the Answer should be Option 1 & 2 (from top).

But according to "Check Answer" it's Option 1,2 & 3 which is wrong according to the logic given in the solution pdf.

Please validate my query

I checked the forum...they have explained why D is the right option:

Hello,

For question 11 option D given that size S is median, since size S is the smallest size for it to be median at least 22 jerseys should be having size of S. If frequency of size S is greater than 22 it means that it is the mode because it is greater than half of total frequency (43).
