B Correct answer
Explanation

Equation I: 15x² + 18x + 3 = 0. Dividing by 3: 5x² + 6x + 1 = 0. Factorizing: (5x + 1)(x + 1) = 0. So x = -1/5 or x = -1. Equation II: 12.5y² - 24y + 16 = 0. Multiplying by 2: 25y² - 48y + 32 = 0. Factorizing: (5y - 8)(5y - 4) = 0. So y = 8/5 = 1.6 or y = 4/5 = 0.8. When x = -1 or -0.2 and y = 0.8 or 1.6, we have x < y in both cases. Therefore x ≤ y is correct.
