$Assertion$ : There is a stage when frictional force is not needed at all to provide the necessary centripetal force on a banked road.
$Reason$ : On a banked road,due to its inclination the vehicle tends to remain inwards without any chances of skidding.

  • A
    If both $Assertion$ and $Reason$ are correct and the $Reason$ is a correct explanation of the $Assertion$.
  • B
    If both $Assertion$ and $Reason$ are correct but $Reason$ is not a correct explanation of the $Assertion$.
  • C
    If the $Assertion$ is correct but $Reason$ is incorrect.
  • D
    If both the $Assertion$ and $Reason$ are incorrect.
