Answer: C) dissolved sodium sulfate and water

Explanation: When the indicator changes its color, it indicates that the endpoint of the titration has been reached out and that a complete reaction of neutralization has been met between all the molecules of NaOH and all the molecules of H2SO4, therefore, the final products will be only dissolved sodium sulfate and water.
