Which single transformation below would have the same effect as rotating the point (-3,4) by 180 degrees around the origin and then reflecting it in the y-axis?

First i will draw the original point in red
the rotation of 180° will give us the point (3,-4) the blue point
next, we reflect this point in the y-axis, the green point
if we see only the red point and the green point the transformation is equivalent to a reflection in the x-axis
the correct answer is 1
