Answer: The correct option for the chemical equation  is 1.
 is 1.
The correct option for the chemical equation  is 3.
 is 3.
Explanation:
- For the chemical equation:

 is a weak acid and hence will not dissociate into ions whereas LiOH is a strong base and will easily dissociate into ions.
 is a weak acid and hence will not dissociate into ions whereas LiOH is a strong base and will easily dissociate into ions.
The product  is soluble in water and hence, will dissociate into its respective ions. Hence, the ionic equation for this reaction is:
 is soluble in water and hence, will dissociate into its respective ions. Hence, the ionic equation for this reaction is:

Net ionic equation becomes:

So, the correct option is 1.
