Answer:
option 4 :Small bubbles of Hydrogen Gas appear on the surface of zinc piece
Explanation:
When dilute hydrochloric acid is added to granulated zinc placed in a test tube, a colourless and odourless gas is evolved with bubbles.
The chemical reaction can be written as:
Zn + 2HCl → ZnCl2+ H2
Hence, the correct option is 4
