The instance of a relation schema R (A, B, C) is given in the table.
We can conclude that
  • a)
    A functionally determines B and B functionally determines C
  • b)
    A functionally determines B and B does not functionally determine C
  • c)
    A does not functionally determine B and B does not functionally determine C
  • d)
    B does not functionally determine C
Correct answer is option 'D'. Can you explain this answer?

The instance of a relation schema R (A, B, C) is given in the table.We...
When , A functionally determines B but it cannot be true for the entire relation.
When , B does not functionally determine C and as well as A does not functionally determine C.
Hence, option 4 is correct.
