Which of the following concerning the 2-D lattice provided below is/are correct?
1)One possible unit cell contains a single A and a single $\bullet$.
2)More than one unit cell which reproduces this lattice is possible.
3)One possible unit cell contains four A's and four $\bullet$'s.

1) One unit cell is made up of one F1F1F1S1F1F1F10 and one F1F1F1S1F1F1F10. This is because one unit cell must contain all the atoms required to recreate the entire lattice, and this pairing of atoms is necessary to do so. 
2) There is only one possible unit cell that reproduces this specific lattice, as the arrangement of atoms is fixed and cannot be shifted in any way that would allow for another valid unit cell. 
3) A unit cell does not contain multiple F1F1F1S1F1F1F10's and F1F1F1S1F1F1F10's. This statement is incorrect as it goes against the definition of a unit cell.
