A series is given with one term missing. Select the correct alternative from the given ones that will complete the series.
RSK, TVM, VYO, XBQ, ?

The logic here is

R + 2 = T $$\longrightarrow\ $$ T + 2 = V $$\longrightarrow\ $$ V + 2 = X $$\longrightarrow\ $$ X + 2 = Z

S + 3 = V $$\longrightarrow\ $$ V + 3 = Y $$\longrightarrow\ $$ Y + 3 = B $$\longrightarrow\ $$ B + 3 = E

K + 2 = M $$\longrightarrow\ $$ M + 2 = O $$\longrightarrow\ $$ O + 2 = Q $$\longrightarrow\ $$ Q + 2 = S

$$\therefore\ $$The missing term in the series is ZES.

Hence, the correct answer is Option D
