B Correct answer
Explanation

Discriminant D = b^2 - 4ac. For 3x^2 + 5x + 2 = 0, a=3, b=5, c=2. D = 5^2 - 4(3)(2) = 25 - 24 = 1.

AI explanation

The discriminant of a quadratic equation ax^2 + bx + c = 0 is found using the formula b^2 - 4ac. For the equation 3x^2 + 5x + 2 = 0, we substitute the coefficients to get (5)^2 - 4(3)(2). Calculating this gives 25 - 24 = 1.
