Juana mailed at least one letter on each day last week. Was the total number of letters that Juana mailed on the 7 days greater than 27
(1) Juana mailed fewer than 8 letters on each of the 7 days
(2) Juana mailed a different number of letters on any two of the 7 days
I answered E (Both options together is not sufficient) but the answer key has marked it wrong and gave the answer as B (Option 2 is sufficient). I have no answer explanation for GMAT official mock tests. Please help

she mailed a different number of letters on 2 of the 7 days
No 2 days had the same number of letters. So - 1, 2, 3, 4, 5, 6, 7, 8 = 28

I think when it says: 'she mailed a different number of letters on 2 of the 7 days'. It means that if you select any 2 particular days in the week, the number of letters sent would never be the same. By that logic, the minimum number of letters mailed was: 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28
Therefore answer is B
