It's B. Chlorobutane

In explaining this answer, I'd test the students knowledge of what a homologous series is. And then we'd draw out the alternative answers and I'd ask the student to explain why...

The atomic number is equal to the number of protons in an atom. The number of protons in an atom is equal to the number of electrons in an atom so the number of electrons in nitrogen is 7 electrons
