  1. If x > y

  2. If x ≥ y

  3. If x < y

  4. If x ≤ y

  5. If x = y or relationship cannot be established

C Correct answer
Explanation

Solve 4x² = 49 to get x = ±3.5. For 9y² - 66y + 121 = 0, note this is (3y - 11)² = 0, giving y = 11/3 ≈ 3.67. Since x = ±3.5 and y ≈ 3.67, we have x < y (as 3.5 < 3.67 and -3.5 < 3.67). The relationship is consistently x < y.
