Answer #1

Generally, at the time of excitation; the electron jumps to higher energy level. The excited electron gets captured by the primary electron acceptor, which is found near P680. This way, the oxidised P680 gets reduced by the electron, which forms out of water. The oxidised P680 has a redox potential of approximately, 1.3 V

Hence, the correct option is +1V

About the incorrect options-

As it has been said in the sources and papers, the redox potential of P680 is +1V

Hope it helps, Good luck !!!!
