Oxygenic photosynthesis occurs in

Which wavelength of light carries out photosynthesis in bacteria?

Statement-$I$: When $PS-II$ is functional,the electron is circulated within the photosystem and photophosphorylation occurs due to the cyclic flow of electrons.
Statement-$II$: The stroma lamellae membranes lack $PS-I$ as well as $NADP$ reductase enzyme.

The balance between $CO_2$ and $O_2$ in the atmosphere is maintained by:

$A -$ Productivity of $C_3$ plants is higher than $C_4$ plants.
$R -$ Photorespiration occurs in $C_3$ plants.

Which of the following photosynthetic bacteria possess both $PS-I$ and $PS-II$?
