1) Since 3 members sold the 6 tickets , therefore the worst case would be when all sells the same number of tickets i.e, 2. SO Sufficient
2) Since no 2 members sold the same number of tickets , therefore even if I take one member sold 0 tickets so the numbers would be 0 ,1 and 2. So Sufficient.

Hence IMO D

(1) The 3 members sold a total of 6 tickets yesterday

The various combinations are 6,0,0 ; 5,1,0 .....2,2,2 So, Sufficient !

(2) No 2 members sold the same number of tickets

Least number of tickets one has sold = 0
Next Least = 1 (as no two members sold the same number of tickets, the next least cannot be 0)
Next Least = 2 (as no two members sold the same number of tickets, the next least cannot be 1)

From the above, We know for sure that at least one has sold more than 2 tickets.

Option D
