Which of the following are the results obtained when zinc reacts sodium hydroxide?

The reaction between metal and a base results in salt formation and the evolution of Hydrogen gas (H₂). Zinc (Zn) is a metal and Sodium hydroxide (NaOH) is a base.
When  Zn metal is added to NaOH, it results in the formation of Sodium zincate (Na₂ZnO₂) salt along with Hydrogen gas. The reaction between Zinc and Sodium hydroxide is:
Zn(s)+2NaOH(aq) $\to$Na₂ZnO₂ (aq) + H₂ (g)

When Zinc reacts with Sodium hydroxide, the products formed are Sodium zincate and Hydrogen gas.
