The logic here is

T - 4 = P $$\longrightarrow\ $$ P - 4 = L $$\longrightarrow\ $$ L - 4 = H $$\longrightarrow\ $$ H - 4 = D

R - 4 = N $$\longrightarrow\ $$ N - 4 = J $$\longrightarrow\ $$ J - 4 = F $$\longrightarrow\ $$ F - 4 = B

O - 4 = K $$\longrightarrow\ $$ K - 4 = G $$\longrightarrow\ $$ G - 4 = C $$\longrightarrow\ $$C - 4 = Y

$$\therefore\ $$The missing term in the series is HFC

Hence, the correct answer is Option D
