Step-by-step explanation:

Step 1:  List out all of the formulas for the trigonometric functions

sin(x) = opposite/hypotenuse

cos(x) = adjacent/hypotenuse

tan(x) = opposite/adjacent

Step 2:  Find the value of h

cot(68) = 13/h is FALSE

sin(68) = h/unknown is FALSE

tan(68) = h/13 is TRUE

Answer: The correct option would be D
