Correct Answer

Explanation

The mixture of gases likely to burn in a flame is hydrogen and neon. When hydrogen burns, it reacts with oxygen to produce water vapor and heat. Neon, being an inert gas, does not participate in the combustion process. Therefore, a mixture of hydrogen and neon is likely to burn in a flame.
