    B. h (x) = 2x^2 - 3x + 3

    Step-by-step explanation:

    Given

    f (x) = 3x+5

    g (x) = 2x^2 - 6x - 2

    h (x) is sum of the functions f (x) and g (x)

    Thus,

    h (x) = f (x) + g (x)

    substituting value of f (x) and g (x) as given above we have

    h (x) = 3x+5 + 2x^2 - 6x - 2

    as (3x - 6x = - 3x and 5 - 2 = 3), we have

    h (x) = 2x^2 - 3x + 3

    Thus, correct answer is option B. h (x) = 2x^2 - 3x + 3.
