Polarimeter is used to determine compounds.
1 $\mathrm{D}$ and $\mathrm{L}$ configuration
2 $\mathrm{d}$ and $l$ configuration
3 $\mathrm{R}$ and $\mathrm{S}$ configuration
4 Both $\mathrm{D}$ and $\mathrm{L}$ as well as $\mathrm{d} \& l$ configuration
Explanation:
(B): Polarimeter is used to determine $\mathrm{d}$ and $l$ configuration of the compound. A polorimeter is a scientific instrument used to measure the angle of rotation caused by passing polarized light through an optically active substance. Thus it can be used to obtain $\mathrm{d}$ and $l$ configuration.
