The question asks for the correct structure of bromoform, which is CHBr₃. Bromoform is a haloform compound where three hydrogen atoms of methane (CH₄) are replaced by bromine atoms. Its molecular formula is CHBr₃, and its structure is tetrahedral, similar to methane, with carbon at the center bonded to one hydrogen and three bromine atoms. The correct option is the one showing a central carbon single-bonded to one H and three Br atoms.

Final Answer: ${\mathrm{CHBr}}_3$
