B Correct answer
Explanation

For x^2 - 9x + 18 = 0, the product of roots is 18. If one root is 6, the other root is 18/6 = 3.

AI explanation

Using the relationship between roots and coefficients, the product of the roots equals c/a, so 6 times the other root equals 18/1. Dividing 18 by 6 gives the other root as 3.
