8.
A metal (more reactive than copper) reacts with hydrochloric acid to form a metal and hydrogen gas, i.e.
metal + HCl → metal chloride + hydrogen

Compare with the given equation : X(s) + 2HCl(aq) → XCl₂(aq) + H₂(g)
It can be deduced that X is a metal (in which the atoms are held together by metallic bond), and XCl₂ is a metal chloride (in which the metal ions and chloride ions are held together by ionic bond.).

The answer is : C. metallic ionic
