Final answer:
The volume of NaOH consumed at the endpoint would be 5 mL.
Step-by-step explanation:
In a titration, the volume of NaOH consumed at the endpoint is equal to the volume of sulfuric acid being titrated. Therefore, in this case, since you are titrating 5 mL of sulfuric acid solution, the volume of NaOH consumed at the endpoint would also be 5 mL (option A).
