Island biogeography theory states that the number of species on an island is determined by immigration rates of new species to the island and extinction rates of species on the island. Immigration rates to an island decline as its distance from the mainland increases and extinction rates decrease with increasing island size. When the immigration and extinction rates on an island are equal, the number of species on the island reaches equilibrium.

Which of the following gives the correct combination of distance (near and far) and area (small and large) of islands where species $\left({\mathrm{S}}_1-{\mathrm{S}}_4\right)$ occur?
