Solution
The correct option is A Aqua Regia
Aqua regia is a mixture of concentrated nitric and hydrochloric acids in a ratio of 1:3 that can dissolve noble metals such as gold, platinum and palladium, even though the metals are not soluble in either acid alone. It is a yellow-orange fuming liquid which is often termed as royal water.
