Solution:The pattern followed here is :For the first letter of each word
O - 3 = L, L - 3 = I , I - 3 = F, F - 3 = C
For the second letter of each word
L + 5 = Q, Q + 5 = V, V + 5 โ A, A + 5 = F
For the third letter of each word
J - 3 = G, G - 3 = D, D - 3 = A, A - 3 = X
For the fourth letter of each word
B + 5 = G, G + 5 = L, L + 5 = Q, Q + 5 = V
So, we get LQGG.
Hence, "LQGG" is the correct answer.
