B Correct answer
Explanation

The pattern is that the digits of each number add up to consecutive numbers: 263 (2+6+3=11), 393 (3+9+3=15), 482 (4+8+2=14), 583 (5+8+3=16), 661 (6+6+1=13). The odd one is 583 because 16 doesn't fit the pattern - all others sum to 11, 13, 14, or 15 (consecutive or near-consecutive), while 583's sum of 16 breaks this sequence.
