B Correct answer
Explanation

The series follows a pattern where the difference between consecutive terms decreases by 5 each time: 163-125=38, 125-92=33, 92-64=28. The next difference should be 28-5=23, so 64-23=41. This is a decreasing arithmetic progression with a constant second-order difference.
