(i) Accumulation of \[{{K}^{+}}\] ions in the guard cells does not require energy. |
(ii) A high pH favours stomatal opening. |
(iii) Movement of chloride ion into guard cells as in response to the electric differential created by \[{{K}^{+}}\] ions. |
(iv) With entry of several \[{{K}^{+}}\] ions and chloride ions, water potential of guard cell increases. |

A) (i) and (iii)
B) (i) and (ii)
C) (ii) and (iii)
D) (iii) and (iv)
