If “he loves coffee“ is coded as 123; “coffee has caffeine” is coded as 245; “he coffee caffeine” is coded as 125 and “ caffeine is bad” is coded as 567 then “he” is represented by:

Correct option is D

Given:
1. “he loves coffee “is coded as 123;
2. “coffee has caffeine” is coded as 245;
3. “he coffee caffeine” is coded as 125
4. “caffeine is bad” is coded as 567
In the 1st and 3rd
"he loves coffee" is coded as 123
"he coffee caffeine" is coded as 125
We see:
"he" and "coffee" are in both sentences, so the common codes between 123 and 125 are 1 and 2.
Since "coffee" also appears in "coffee has caffeine" coded as 245, "coffee" must be either 2, 4, or 5.
From the codes:
If "coffee" was 2, the remaining would be "he" is either 1 or 3.
If "coffee" was 4 or 5, it would conflict with the previous identifications.
Since "he" is in "he loves coffee" (123) and "he coffee caffeine" (125), the remaining consistent code identifying with "he" without conflict is:
"he" = 1
Thus, the answer is (d) 1.
