The question is which of these is equal to cos 19. Since there are no choices given, the only answer I could give is the approximate answer.

cos 19° = 0.9455

If the choices were other forms of trigonometric functions, you can use the trigonometric identities to prove that they are equal to cos 19° or you can use your calculator and input the choices and see which would result to 0.9455.
