- Only II
- Only I and III
- All I, II and III
- Either I only or II only
- None of these
Answer: Option 5
To find the code for 'we', we need to have any of the following: (i) 'We are friends' should have only 'We' common with another statement, as in II; (ii) 'We are friends' should have only 'are' and 'friends' common with another single or two statements, as in I and III. Thus, we need Either II only or I and III only.
