Solution

The correct options are
A Zinc slowly begins to dissolve into the acid.
C Bubbles are seen near the copper rod.
Zinc and Copper metal rods when dipped into a solution of sulphuric acid generate electricity. After sometime, we can see the zinc rod slowly dissolving into the acid and (Hydrogen) bubbles are seen near the copper rod. The given situation is an example of the process of electrolysis.
