B Correct answer
Explanation

This series shows: 15 ÷ 14 ≈ 1.07, 20 ÷ 15 ≈ 1.33, 39 ÷ 20 = 1.95. The pattern of multiplication factors breaks here. Continuing 20 × 1.33 = 26.6, not 39. The term 39 appears to be incorrect - it should be approximately 26.6-27 to continue the pattern. 39 is the wrong term.
