Pretty sure the answer is A on Plato
Explanation:
I looked it up, and it said that raising the temperature would cause the equilibrium to shift left.
To find the ratio of the the combination for the ion, write the charge of the cation as the subscript for the anion, and the charge of the anion as the subscript of the cation. This will make the charges effectively cancel and you will be left with a neutral ionic compound. Remember, that an ionic compound is made up of a metal and a nonmetal.
For Ca2+ and Cl-, you will get the neutral compound to be CaCl₂.

Also, 
Applying the equation as:
Where,
h is Plank's constant having value 
c is the speed of light having value 
is the wavelength of the light being bombarded
Given, 
is the binding energy or threshold energy
is the kinetic energy of the electron emitted. = 
Thus, applying values as:
