When N-13 undergoes positron emission, it loses a positron (a particle with the same mass as an electron but with a positive charge) and becomes C-13. The correct notation for this is:

N-13 -> C-13 + e+ (positron)

Option B represents C-13, as evidenced by the atomic number (6) and mass number (13).
