The molecules can be ordered by the number of atoms of each element, starting with the smallest. The order from smallest to largest is: S1S1P0 < S1U1P1 < SeS1U1P12 < ClS1U1P1 < NaS1U1P1. Therefore, the correct order from smallest to largest molecule is: NaS1U1P1+S1S1P0 < KS1U1P1+S1S1P0 < ClS1U1P1-S1S1P0 < SS1U1P12-S1S1P0 < SeS1U1P12-S1S1P0. Choice B lists the molecules in this order.
