BVUIFOUJD : BWUJFPUKD : : HFOVJOF : ?

BVUIFOUJD : BWUJFPUKD shows the pattern: +1, +2, +1, +2, +1, +2, +1, +2, +1 (alternating +1 and +2): B(2)+1=W(23)? No, that's not right. Let me recount: B(2) to B(2) is 0, V(22) to W(23) is +1, U(21) to U(21) is 0, I(9) to J(10) is +1, F(6) to F(6) is 0, O(15) to P(16) is +1, U(21) to U(21) is 0, J(10) to K(11) is +1, D(4) to D(4) is 0. So pattern is 0, +1, 0, +1, 0, +1, 0, +1, 0. Applying this to HFOVJOF: H(8) stays H, F(6)+1=G, O(15) stays O, V(22)+1=W, J(10) stays J, O(15)+1=P, F(6) stays F. This gives HGOWJPF, which is option B.
