The compound x is sodium hydroxide
Therefore a is sodium zincate Na2ZnO2
B is sodium chloride NaCl
C is sodium acetate CH3COONa

Dear Yashanshu,
You forgot to mention supposed reactions. I'll write down that for you.
X + Zn --> A + H2
X + HCl --> B + H2O
X + CH3COOH --> C + H2O
● Answers -
X => sodium hydroxide (NaOH)
A => sodium zincate (Na2ZnO2)
B => sodium chloride (NaCl)
C => sodium methanoate (CH3COONa)
● Reactions -
(1) NaOH (X) reacts with Zn to form sodium zincate (A) & H2 gas.
2NaOH + Zn --> Na2ZnO2 + H2
(2) NaOH (X) reacts with HCl to form sodium chloride (B) & water.
NaOH + HCl --> NaCl + H2O
(3) NaOH (X) reacts with CH3COOH to form sodium ethanoate (C) & water.
NaOH + CH3COOH --> CH3COONa + H2O
Thanks for asking..
