In this exercise, an Assertion is followed by the Reason. Mark the suitable answer from the given:
Assertion(A): From the figure, \(AB = 7 \ m\), \(\angle BAC = 60^{\circ}\), then \(AC = 14 \ m\).
Reason(R): \(cos \ \theta = \frac{\text{Adjacent side}}{\text{Hypotenuse}} = \frac{AB}{AC}\) where \(\theta\) is the angle \(BAC\).
Which of the following is the correct option for the given statements?
