Que. | Let G(x) be the generator polynomial used for CRC checking. What is the condition that should be satisfied by G(x) to detect odd number of bits in error? |

a. | G(x) contains more than two terms |

b. | G(x) does not divide 1+x^k, for any k not exceeding the frame length |

c. | 1+x is a factor of G(x) |

d. | G(x) has an odd number of terms |

Answer:1+x is a factor of G(x) |
