B Correct answer
Explanation

This alternating series has interleaved patterns: Positions 1,3,5,7 add increasing amounts: 47+(-3)=44 is wrong. The actual pattern is: first series (positions 1,3,5,7): 47, 45, 33, 3 with differences -2, -12, -30 (decreasing by 10, then 18 doesn't fit cleanly). Second series (positions 2,4,6): 44, 46, 57 with differences +2, +11. 57 appears to be the odd one out based on position.
