  1. X > Y

  2. X < Y

  3. X ≤ Y

  4. X ≥ Y

  5. X = Y or the relationship cannot be established

A Correct answer
Explanation

Equation I: x² - 20x + 91 = 0 factors to (x-13)(x-7)=0, so x=13 or x=7. Equation II: y² + 16y + 63 = 0 factors to (y+7)(y+9)=0, so y=-7 or y=-9. Since all x values (13,7) are greater than all y values (-7,-9), X > Y.
