In the following Questions, the Assertion and Reason have been put forward. Read the statements carefully and choose the correct alternative from the following:
(a) Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion.
(b) The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion.
(c) Assertion is true but the Reason is false.
(d) Both Assertion and Reason are false.
Assertion: \( \cos 47^{\circ}=\sin 43^{\circ} \)
Reason: \( \sin \theta=\cos \left(90^{\circ}+\theta\right) \), where \( \theta \) is an acute angle.
