IMO D

If we consider that no one is having B'day in june then

11* 6 (atmost) = 66 jamborress.

So it is very much possible that noone has a B'day in the Month of June

1. Oct > Nov (no of B'day)

if there are 6 b'days in oct then there would be 'atmost' 5 b'days in NOV.

there fore in month of June there must be 'atleast' 1 b'day

2. same as above
