Answer:  The correct option is (a) 2x^2+3x-5.

Step-by-step explanation:  We are given to find the quotient in the following division :

Q=\dfrac{2x^3-3x^2-14x+15}{x-3}.

To find the quotient, first we will try to factorize the numerator and then we will try to divide by the denominator.

We have

Q\\\\\\=\dfrac{2x^3-3x^2-14x+15}{x-3}\\\\\\=\dfrac{2x(x-3)+3x(x-3)-5(x-3)}{x-3}\\\\\\=\dfrac{(x-3)(2x^2+3x-5)}{(x-3)}\\\\=2x^2+3x-5.

Thus, the required coefficient is 2x^2+3x-5.

Option (a) is CORRECT.
