Detailed Solution

Concept: Lead chloride and nitric acid will form in this reaction when diluted HCl is added to a solution of lead nitrate. Lead nitrate and diluted hydrochloric acid are the reactants in the aforementioned reaction, which involves a chemical change in the components. Lead chloride and nitric acid are byproducts of the novel chemical.
The equation for the chemical reaction provided can be expressed as

Now, to balance the equation, we have to determine the number of atoms in each element on the LHS and RHS of the arrow and compare them. As we can see, all the elements in the given reaction are balanced except hydrogen and chloride. So, we will balance them and the final reaction then would be

Hence, the correct answer is option 3.
