Q. |
## In conics, the is revolving to form two anti-parallel cones joined at the apex. |

A. | ellipse |

B. | circle |

C. | generator |

D. | parabola |

Answer» C. generator | |

Explanation: in conics, the generator is revolving to form two anti-parallel cones joined at the apex. the plane is then made to cut these cones and we get different conic sections. if we cut at right angles with respect to the axis of the cone we get a circle. |
