Which one of the following organisms does not evolve oxygen during photosynthesis?

Assertion : Photosynthesis is important due to two reasons.
Reason : Photosynthesis is the primary source of food on earth and responsible for the release of oxygen from green plants.

Analogy type questions:
$(1)$ $C_4$ plants : Show $CO_2$ saturation at $360 \,\mu l L^{-1}$ :: $C_3$ plants : Show $CO_2$ saturation at concentrations above ............
$(2)$ Green plants : $H_2O$ as hydrogen donor :: Green sulfur bacteria : ............

Which of the following statements with regard to photosynthesis is/are correct?
$I$. In $C_{4}$-plants,the primary $CO_{2}$ acceptor is $PEP$.
$II$. In the photosynthetic process,$PS-II$ absorbs energy at or just below $680 \;nm$.
$III$. The pigment that is present in the Pigment System-$I$ is $P680$.

Out of the two statements given here $:-$
$(A) \ C_4$ plants are more effective in productivity as compared to $C_3$ plants.
$(B) \ C_3$ plants show photorespiration at high $CO_2$ concentration.
