Statement A (Assertion): The value of each of the trigonometric ratios of an angle does not vary with the length of the length of the sides of the triangle if the angle remains the same.
Statement R (Reason): In right-angled triangle ABC angleB = 90° and angleA = theta, sinTheta = BC/AC<1 and cosTheta= AB/AC<1, as hypotenuse is the longest side.
A. Both A and R are true, and R is the correct explanation of A.
B. Both A and R are true, but R is not the correct explanation of A.
C. A is true, but R is false.
D. Both A and R are false.
