The correct answer is option 1 - Displacement reaction
It is a single replacement reaction where 1 atom of Zinc metal displaces 2 H+ ions from the hydrochloric acid to form hydrogen gas and zinc chloride, a salt.
The reaction is also a redox reaction as zinc metal begins the process as a pure metal with an ionic charge of zero and loses an electron as it reacts with the acid to become a positively charged zinc ion through oxidation. At the same time, hydrogen undergoes reduction by gaining an electron to become a neutral molecule.
