Concept:The series alternates adding 4 and 5 to letter positions.Explanation:Convert letters to positions: A=1, E=5, J=10, N=14, S=19, W=23.Differences: 5−1=4, 10−5=5, 14−10=4, 19−14=5, 23−19=4.So the pattern is +4, +5, +4, +5, +4, hence next is +5.23+5=28.Since there are 26 letters, 28−26=2, which is B.
