To find the product, each term in the first parenthesis is multiplied by each term in the second parenthesis and then the results are combined. The correct product is $-15x^4 - 27x^2y - 3x^2z + 54y^2 - 9yz$, which matches option C.

Find the Product (−3x2−9y)(5x2−6y+z)\left( - 3 x ^ { 2 } - 9 y \right) \left( 5 x ^ { 2 } - 6 y + z \right)(−3x2−9y)(5x2−6y+z)
