From the following instance of a relation scheme R (A, B, C), we can conclude that :

A | B | C |

1 | 1 | 1 |

1 | 1 | 0 |

2 | 3 | 2 |

2 | 3 | 2 |

A | A functionally determines B and B functionally determines C |

B | A functionally determines B and B does not functionally determine C |

C | B does not functionally determine C |

D | A does not functionally determine B and B does not functionally determine C |
