Answer:

The correct answer is option B which is chemical change.

Explanation:

  • A physical change means any change in compound's physical properties like change in shape, phase or temperature during a reaction.
  • A chemical change means change in chemical composition which leads to production of new compound.
  • A phase change means conversion of state of a particular compound, for example from liquid to gaseous state.
  • Hence in this reaction gas is produced, so its a chemical change.
