In a certain code language if SUNSET is written as TVOTFU, how will SUNRISE be written in the same code language?

TVOSJTF

The logic;

S (19) +1 = T 20

U (21) +1 = V 22

N (14) +1 = O 15

S (19) +1 = T 20

E (5) +1 = F 6

T (20) +1 = U 21

Similarly,

S (19) +1 = T 20

U (21) +1 = V 22

N (14) +1 = O 15

R (18) +1 = S 19

I (9) +1 = J 10

S (19) +1 = T 20

E (5) +1 = F 6

Thus, TVOSJTF is right answer.
