Answer:
Zinc is Answer
Symbol is Zn
Zinc will react with Sodium Hydroxide from Sodium Zincate. In this reaction, Zinc will not displace sodium from sodium hydroxide, but will displace Hydrogen as shown below: This reaction is accompanied by an evolution of Hydrogen gas.

+H ²
Zinc metal reacts with hydrochloric acid producing zinc chloride and hydrogen gas. Bases also react with certain metals like zinc or aluminum for example to produce hydrogen gas .
When zinc (Zn) react with excess sodium hydroxide ( Na OH ), the compound sodium zincate ( Na² Zn O² ) along with hydrogen gas is formed. Since, Zinc is amphoteric, it reacts with NaOH to form sodium zincate with the evolution of hydrogen gas. This reaction takes place at a temperature near 550°C.
Zinc react with sodium hydroxide to produce zincate sodium and hydrogen. This reaction takes place at a temperature near 550°C.
Zn + 2NaOH → Na2ZnO2 + H2
When NaOH reacts with zinc it releases water.
When a metal like zinc reacts with a base like NaOH, hydrogen gas is released which burns with a pop sound.
2NaOH+Zn→Na

ZnO ³
+H ²
Sodium Zincates
So, the correct option is Zinc ( Zn )
