    Answer:

    Option b

    Step-by-step explanation:

    We have been given the discriminant 12

    We have to choose the equation which will satisfy the given discriminant.

    We will consider all the given equation one by one

    First we will take option a which is

    Discriminant from the equation we will find by the formula

    Here, a=-1,b=8 and c=2 on substituting the values we will get

    Hence, option a is incorrect.

    Now, we will consider option b which is

    Here, a=2,b=6 and c=3 on substituting the values we get

    Hence, option b is correct

    Therefore, option b is the required answer.
