    The answer to your question is letter C. 7y³ + 7n²y² - 22y²

    Step-by-step explanation:

    y² (4y + 7n² + 2) - 3y² (-y + 8)

    Multiply

    4y³ + 7n²y² + 2y² + 3y³ - 24y²

    Use the associative property for like terms

    (4y³ + 3y³) + (2y² - 24y²) + 7n²y²

    Simplify like terms

    7y³ - 22y² + 7n²y² or 7y³ + 7n²y² - 22y²
