When the final rays are converging then the image of the object will be real. It is because the converging rays are always formed in front of the mirror (concave mirror). The image formed is called real image because the final rays are actually converging in front of mirror to form the image. While the virtual image is formed when the final rays are diverging and they appear to be converging beyond the mirror but they never converge in real.

Hence option A is correct.
