Assertion: The curve in the graph below is not a one-one function:

Reason: If any straight line parallel to y-axis does not cut the curve at more than one point, then that curve represents a function.

Assertion (A): The curve in the graph below is not a one-one function: Reason (R): If any straight line parallel to y-axis does not cut the curve at more than one point, then that curve represents a function.
  • (a)Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
  • (b)Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
  • (c)Assertion (A) is true, but Reason (R) is false.
  • (d)Assertion (A) is false, but Reason (R) is true.
