Read the following statements:
$(a)$ $F_{0}$ part of $ATP$ase is associated with the breakdown of the proton gradient.
$(b)$ $A$ $H^+$ carrier contributes to the creation of the proton gradient.
$(c)$ Movement of electrons in $ETS$ is coupled to the pumping of protons into the lumen.
$(d)$ Formation of $NADPH + H^+$ is related to the creation of the proton gradient.
How many of the above statements are correct?

The following $(I-VI)$ are the main steps of chemiosmotic $ATP$ synthesis in the light reaction. Arrange them in the correct order:
$I$. $H^+$ concentration gradient established
$II$. $H^+$ diffuses through $ATP$ synthase
$III$. Carriers use energy from electrons to move $H^+$ across the membrane
$IV$. Electrons from $PS-II$ pass along the electron transport chain
$V$. Light excites electrons in $PS-II$
$VI$. Energy of $H^+$ flow is used by $ATP$ synthase to make $ATP$
