A Correct answer
Explanation

Nitric acid is sometimes referred to as 'Aqua Fortis' in historical and industrial contexts. The term 'Aqua Gold' appears to be a confusion between 'Aqua Fortis' (strong water - nitric acid) and 'Aqua Regia' (royal water - mixture of nitric and hydrochloric acids that can dissolve gold). Among the options, nitric acid is the closest match.
