1. Identify the type of reaction implied

   The options given are different brominating conditions. Such questions in haloalkanes/haloarenes commonly ask which reagents allow addition of bromine to an alkene/unsaturated system versus electrophilic substitution on an aromatic ring.

   The set of reagents suggests that the given reaction is one that can occur with molecular bromine under non-aqueous conditions and also under Lewis-acid catalysis.

2. Examine each reagent

   (a) Bromine water

   Bromine water is used mainly for:

   • testing unsaturation,
   • reaction with strongly activated aromatic rings like phenol/aniline,
   • hydroxybromination in some cases because water is present.

   It is not the usual condition for the bromination reaction implied here if the required product is obtained specifically by bromine addition/substitution under anhydrous conditions. Hence, this is not suitable.

   So, (a) is not correct.

   (b) $Br_2$ in $CS_2$, 273 K

   $CS_2$ is an inert nonpolar solvent. Bromination commonly occurs in such solvents for addition/substitution reactions without interference from water.

   So, (b) is correct.

   (c) $Br_2/FeBr_3$

   $FeBr_3$ is a Lewis acid and generates the electrophile $Br^+$ from bromine, enabling bromination in aromatic systems.

   So, (c) is correct.

   (d) $Br_2$ in $CHCl_3$, 273 K

   $CHCl_3$ is also an inert organic solvent commonly used for bromination reactions.

   So, (d) is correct.

3. Collect the correct statements

   Correct reagents are: $(b),(c),(d)$

4. Match with the given options

   • A: (b) and (d) only incorrect
   • B: (a) and (c) only incorrect
   • C: (b), (c) and (d) only correct
   • D: (a), (b) and (d) only incorrect

Therefore, the correct answer is C.
