A store sells a variety of kits for building molecular models. The kits are described by the diagram below. Each circled letter represents a box of 6 model atoms of one element. For example, the circled letter "P" represents a box with 6 model phosphorous atoms.

Which change(s) to one of the kits would make it useful for modeling proteins?

• Kit 1: Add Nitrogen (N) atoms and more Carbon (C) atoms

• Kit 2: Add more Carbon (C) atoms

• Kit 3: Add Nitrogen (N) atoms and remove Phosphorus (P) atoms
