Sudha took lemon juice in two flasks. She put salt in flask I and washing soda in flask II. She observed lots of bubbles in flask II but nothing in flask I. What could be the reason for this?

B In flask II, a chemical change takes place and bubbles of carbon dioxide are seen.
C In flask II, a physical change takes place producing lots of bubbles.
D In flask I, salt reacts with lemon juice and forms a new compound.
