B

its pretty logical ... esp of one is taking all consecutive integers.

you take
1 2 3 4 5 4 6 OR 5 6 7 8 9 10 11

sum of remainders will be 1+2+3+4+5+6+0

Agreed .. B should be the answer.

1 ) range of the reminders is 6 => we can have 6 numbers with reminder 0 and one with reminder 6; or 1 with reminder 0. one with reminder 6 and rest being anything etc.. not sufficient

2 ) The seven numbers selected are consecutive integers = > the reminders will be 0,1,2,3,4,5,6 ( not necessarily in the order )

very well explained. i could not see that the numbers could be repeated.
