D Correct answer
Explanation

For equation I: x³ = -704969. Since the cube of a negative number is negative, x = -89 because -89 × -89 × -89 = -704969. For equation II: y² = 7921, so y = ±89 (since both 89² and (-89)² = 7921). Comparing x = -89 with y = ±89: x = y when y = -89, and x < y when y = 89. Therefore x ≤ y is always true. D is correct.
