To determine whether the unknown bacterium is a chemotroph, you would want to assess its ability to obtain energy from chemical compounds, rather than from sunlight or photosynthesis.
The most appropriate method from the options listed is:
**B. growing the bacterium in a sulfur solution to see if it breaks the inorganic molecules down.**
This option would help determine whether the bacterium can utilize inorganic compounds as a source of energy, which is a characteristic of chemotrophs.
