Que. | If the following system has non-trivial solution, px + qy + rz = 0 qx + ry + pz = 0 rx + py + qz = 0 then which one of the following options is True? |

a. | p – q + r = 0 or p = q = –r |

b. | p + q – r = 0 or p = –q = r |

c. | p + q + r = 0 or p = q = r |

d. | p – q + r = 0 or p = –q = –r |

Answer:p + q + r = 0 or p = q = r |
