The question is asking which test would be most helpful for a chemist to identify a sample of nitrogen among four elements. The options are:

A) Try to burn each sample
B) Observe the color of each sample
C) Observe the state of matter of each sample
D) Test each sample with a magnet

To answer this question, we need to consider the properties of nitrogen. Nitrogen is a colorless, odorless, tasteless, and mostly inert diatomic gas at standard conditions, constituting 78% by volume of Earth's atmosphere.

Given these properties, the most effective way to identify nitrogen would be to:

C) Observe the state of matter of each sample

This is because nitrogen is a gas at room temperature and pressure, unlike many other elements which are solid or liquid. Therefore, observing the state of matter of each sample would be the most effective way to identify nitrogen.
