d) Potassium metal is the correct answer.
Potassium is an alkali metal that is very strongly reactive and highly electropositive, it very easily displaces Hydrogen gas from the acid and does so very explosively and exothermically.
This reaction cannot be performed in the laboratory as it is very dangerous.
