Correct choice is (c) sine, cosine, tangent, cotangent, secant and cosecant

To explain I would say: Trigonometric ratios are generally defined as the ratios of any two sides of a right-angled triangle and it gives the relation between sides of a right-angled triangle to its appropriate angle. Sine, cosine, tangent, cotangent, secant and cosecant are six trigonometric ratios used in trigonometry.
