Identify the Statement Among the Following That Combines a Correct

Identify the statement among the following that combines a correct cause with a correct effect of that cause.

A) Sulfur atoms are smaller than phosphorus atoms because sulfur has a smaller atomic number
B) The radius of calcium atoms is greater than the radius of magnesium atoms because ground state electrons occupy a higher energy level in calcium than in magnesium
C) Atomic size increases from left to right in a row of the periodic table because density increases in the same direction
D) The relative sizes of silicon atoms and aluminum atoms are not predictable on the basis of nuclear charge and highest occupied energy level because one factor predicts silicon atoms to be larger, and the other factor predicts aluminum atoms to be larger
E) More than one of the above statements combines a correct cause with a correct effect of that cause
