(a) |
If the statement I alone is sufficient to answer the question but the statement II alone is not sufficient. |

(b) |
If the statement II alone is sufficient to answer the question, but the statement II alone is not sufficient. |

(c) |
If both statements I and II together are needed to answer the question. |

(d) |
If either the statement I alone or statement II alone is sufficient to answer the question. |

(e) |
If you cannot get the answer from the statements I and II together but needed more data. |
