Solution

The correct option is B Levitt
Levitt in 1974, proposed a synthetic theory on the mechanism of stomatal movement, taking all earlier observations into account. The observed facts are:
(a) During opening of stoma, starch disappears from the guard cells.
(b) Photoactive opening is dependent on the chloroplast of the guard cells.
(c) Low $C O_{2}$ concentration causes stomatal opening.
(d) High pH in guard cells cause stomatal opening.
(e) There is a direct relation between $K^{+}$ accumulation and stomatal opening.
