Correct Answer: 52

Solution : Given:
RAT is coded as 39 and MICE is coded as 30.

Add the positional value of RAT, to obtain the required code –
R→18; A→1; T→20
Now add the position values = 18 + 1 + 20 = 39
So, RAT is coded as 39.
And in, MICE is coded as 30 –
M→13; I→9; C→3; E→5
Now add the position values = 13 + 9 + 3 + 5 = 30
So, MICE is coded as 30.
Similarly, follow the same pattern for ZEBRA –
Z→26; E→5; B→2; R→18; A→1
Now add the position values = 26 + 5 + 2 + 18 + 1 = 52

So, ZEBRA is written as 52 in the code language. Hence, the second option is correct.
