Step 1: Note the three ingredients moist air supplies.
Air that has been sitting around a copper vessel for a long time is not just carrying oxygen, it also carries water vapour and carbon dioxide, all three of which take part in the slow surface reaction.
Step 2: Combine them with copper metal. \[ 2\text{Cu} + \text{H}_2\text{O} + \text{CO}_2 + \text{O}_2 \to \text{CuCO}_3\cdot\text{Cu(OH)}_2 \] The product written this way is really a combined salt built from two simpler compounds sitting together.
Step 3: Split the combined formula into its two components.
Reading the formula $\text{CuCO}_3 \cdot \text{Cu(OH)}_2$ carefully shows it is literally copper carbonate joined with copper hydroxide, this is the basic copper carbonate patina seen on old copper statues and vessels.
Step 4: Match with the options.
The green layer is therefore a mixture of these two named compounds together, not any single pure compound. \[ \boxed{\text{Copper hydroxide and Copper carbonate}} \]
