B) This equation has two real solutions, because when taking the square root of 43, there is a positive and a negative solution for ±√43.
When taking the square root of both sides of the equation, we get:
x + 3 = ±√43
This means that x = -3 + √43 and x = -3 - √43 are the two real solutions to the equation. Therefore, the equation has two real solutions.
