The correct statement regarding ethane conformation is:
- ARotation around carbon-carbon bond in ethane molecule is not possible,because ethane molecule contains a pi $(\pi)$ bond between the carbon and carbon and ethane has very low melting point.
- BRotation around carbon-carbon bond in ethane molecule is not possible,because ethane molecule contains both sigma $(\sigma)$ bond,and pi $(\pi)$ bond between the carbon and carbon.
- CRotation around carbon-carbon bond in ethane molecule is possible because of cylindrical symmetry of sigma $(\sigma)$ bond between carbon-carbon atoms.
- DRotation around carbon-carbon bond in ethane molecule is not possible,because ethane molecule contains both sigma $(\sigma)$ bond and pi $(\pi)$ bond between the carbon and carbon and ethane has very high boiling point.

Given below are two statements:
Statement $I$: There are several conformers for $n$-butane. Out of those conformers,the fully eclipsed conformer (dihedral angle $0^{\circ}$) is the least stable and the anti-staggered conformer (dihedral angle $180^{\circ}$) is the most stable.
Statement $II$: As the dihedral angle increases from $0^{\circ}$ to $60^{\circ}$,torsional strain decreases from the fully eclipsed conformer $(X)$ to the gauche conformer $(Y)$.
In the light of the above statements,choose the correct answer from the options given below:
