C Correct answer
Explanation

Salt and water are produced in acid-alkali neutralization reactions. This is a fundamental chemical principle: acid + alkali -> salt + water. The H+ from acid and OH- from alkali combine to form H2O, while the remaining ions form the salt. This reaction doesn't produce CO2, hydrogen gas, or soap.
