Directions: In the following questions, a statement of assertion is followed by a statement of reason. Mark the correct choice as:
(a) If both assertion and reason are true and reason is the correct explanation of assertion.
(b) If bothrassertion and reason are true but reason is not the correct explanation of assertion.
(c) If assertion is true but reason is false.
(d) If both assertion and reason are false.
Assertion : A combination of two simple harmonic motions with arbitrary amplitudes and phases is not necessarily periodic.
Reason : A periodic motion can always be expressed as a sum of infinite number of harmonic motions with appropriate amplitudes.
