Answer:
Step-by-step explanation:
Here, we want to get the balanced equation of the reaction
In a balanced equation of reaction, the number of atoms of each of the elements on each side of the reaction would be the same
Let us consider the options:
a) We have 3 oxygen atoms on the left and 2 on the right, this is not balanced
b) We have 3 atoms of oxygen on the left but 2 on the right
c) This is not balanced. We have 2 atoms of potassium and chlorine on the left but we have 1 atom of each on the right
d) This is balanced as all the elements have same number of atoms on both sides
