In this problem, you are given two functions, f and g. As you can see, f is increasing from negative to positive. This transition from negative to positive happens at x=0. The opposite happens for g, where g is decreasing from positive to negative. This transition from positive to negative happens at x=0.
So the question asks for the best function that fits fg. So the first thing you know is that f and g both have the point (0,0), so 00=0. This means that you can cross out B. What else do you know? Well, notice that f is negative every time g is positive, but f is positive every time g is negative. This means that f*g will always result in a negative number. So look for the function where all values are negative (except for (0,0)). As you can see, this only occurs for A. Thus, the answer is A.
