C)The two quantities are equal.
D)The relationship cannot be determined from the information given.
Here Quantity A : \((x + 2) (x - 3)\) = \(x^2 - x - 6\) = Quantity B
Hence Quantity A = Quantity B

Explanation
Terms in Quantity A:
\((x + 2)(x - 3) = x^2 - 3x + 2x - 6 = x^2 - x - 6\)
The two quantities are equal.

Given that the Quantity A is a multiplication of two linear equations, and Quantity B is a quadratic, and also that the multiplication of the constant terms in the linear factors gives me -6 which is present in Quantity B, there is a high probability that FOILing the linear factors will give me Quantity B, and that is something that I will attempt.
\((x + 2)(x - 3)\)
\(x^2 - 3x + 2x -6\)
\(x^2 - x - 6\)
Quantity A = Quantity B
Answer is Choice C
