Answer:
Statement A. is correct.
Explanation:
If the two sides making an angle Ф in a triangle have the fixed lengths then the length of the third side is proportional to the angle Ф. 
Since the opposite angle of XY(79°) is larger than that of YZ(65°), so XY > YZ. 
Again the opposite angle of YZ(65°) is larger than that of AB(36°), so YZ > AB. 
 {Since the sides containing those angle are same and they are 8 ft} 
Therefore, statement A. is correct. (Answer)
