Solution

The correct option is B
Solution Y is formic acid.

According to pH: solution X is acidic, solution Y is neutral and solution Z is basic.So, acids react with metal to liberate hydrogen, acid and base reacts together to form salt and water. Also acids react with $C a C O_{3}$ to liberate $C O_{2}$ gas. But pH of formic acid is 2.3 and not 7.
