Explanation: Let's break down the code to find the pattern:
* SEEK = 14006
* S = 19
* E = 5
* E = 5
* K = 11
* TREE = 151300
* T = 20
* R = 18
* E = 5
* E = 5
Now, let's look at the positions of the letters in the alphabet and compare them to the code:
* SEEK:
* S(19) -> 14
* E(5) -> 0
* E(5) -> 0
* K(11) -> 6
* TREE:
* T(20) -> 15
* R(18) -> 13
* E(5) -> 0
* E(5) -> 0
The pattern seems to be that the coded number is the alphabetical position minus 5.
* 19-5 = 14
* 5-5 = 0
* 11-5 = 6
* 20-5 = 15
* 18-5 = 13
Now, let's apply this pattern to OPPO:
* O = 15
* P = 16
* P = 16
* O = 15
Applying the pattern (position - 5):
* O(15) -> 15 - 5 = 10
* P(16) -> 16 - 5 = 11
* P(16) -> 16 - 5 = 11
* O(15) -> 15 - 5 = 10
Therefore, OPPO will be coded as 10111110.
The answer is (D) 10111110.
