Solution

The correct option is B CCl4

Due to its symmetrical structure, carbon tetrachloride (CCl4) is non-polar. Its non-polar nature makes it a suitable solvent for dissolving non-polar compounds. Carbon tetrachloride is convenient as a solvent for NMR because it contains no protons, however, its poor dissolving power limits its usefulness. As a solvent, it is well suited for dissolving other non-polar compounds, iodine, fats, and oils.

CCl4 can undergo various reactions like dimerization to Hexachloroethane, reduction to chloroform.

Hence, the correct option is A
