Consider the following statements.
$I.$ The portion of the spectrum between $300-500 \;nm$ is also referred to as Photosynthetically Active Radiation $(PAR)$.
$II.$ Magnesium,calcium and chloride ions play prominent roles in the photolysis of water.
$III.$ In cyclic photophosphorylation,oxygen is not released (as there is no photolysis of water) and $NADPH$ is also not produced.

• A
  $I$ is true; but $II$ and $III$ are false
• B
  $I$ and $II$ are false; but $III$ is true
• C
  $II$ is true; but $I$ and $III$ are false
• D
  $I$ and $II$ are true; but $III$ is false
