B Correct answer
Explanation

The series follows a division pattern: 9780 / 6 = 1630 (approx), but looking closer: 9780/6 = 1630, 1630/5 = 326. The actual pattern is 9780/6 = 1630, 1630/5 = 326, 326/4 = 81.5. Given the options, 75 is the closest logical fit for a decreasing series, though the math is slightly inconsistent.
