  cosine and secant are reciprocal functions .

  So cos y * sec y will be 1.

  For, cos y = 1/sec y.

  So answer is (b) 1.

  To determine the product of sec y and cos y, we can use the trigonometric identity:

  sec y = 1 / cos y

  Let’s substitute this into the expression and simplify:

  (sec y) * (cos y) = (1 / cos y) * (cos y) = 1

  Therefore, the product of sec y and cos y is equal to 1.

  The correct answer is b) 1.
