The correct option is A
10

The value of the remainder of a polynomial of degree greater than or equal to zero, when divide by a linear polynomial x – a is P(a). So, the value of the polynomial at x = -2 is the remainder of 3 $x^{2}$ + 5x + 8.

The value of polynomial 3 $x^{2}$ +5x+8 at x=-2 is 3 ${(- 2)}^{2}$ +5(-2)+8=10
