$II.$ Role of $Na^+$ in stomatal opening is now universally accepted.
$III.$ The water potential of root cells is higher than the water potential of soil.
$IV.$ Capillarity theory is the most accepted theory of water movement through plants.
$V.$ The walls of xylem vessels made up of ligno-cellulose have strong affinity for water molecules.

Which statement about photosynthesis is false?

Read the following four statements ($a, b, c,$ and $d$) carefully and select the option that includes both correct statements.
$(A)$ The $Z$-scheme of light reaction occurs only in the presence of $PSI$.
$(B)$ Only $PSI$ is functional in cyclic photophosphorylation.
$(C)$ Cyclic photophosphorylation results in the synthesis of $ATP$ and $NADPH_2$.
