The number of real zeros are equal to the x-intercepts of the graph. x-intercepts are the points where the graph crosses the x-axis.

From the graph we can see that the function does not cross the x-axis at any point. Hence it has no x-intercept and thus no real zero. Both the zeros will be complex. 

So, the correct answer is option B.
Function has exactly 2 complex solutions.

The graph shows a parabola. A parabola's equation is f(x) = 4a*x^2 + b

This means that 1 value of y  is equal to two values of x

so the answer is D. Function f has two real solutions
