Answer:
Option B is correct.
the value of discriminant is, -7
Step-by-step explanation:
Given the equation: 
To find the value of discriminant 
A quadratic equation is of the form
where a, b and c are coefficient of the equation.
On comparing with given equation we have;
a = 1 , b = 1 and c = 2
then;
Discriminant = 
Therefore, the value of discriminant is, -7
3(-12)-17= 3 times -12 is -36
-36-17= -53
