( A ) The staggered conformation of ethane is more stable than eclipsed conformation, because staggered conformation has no torsional strain
( B ) The eclipsed conformation of ethane is more stable than staggered conformation, even though the eclipsed conformation has torsional strain.
( C ) The staggered conformation of ethane is less stable the an eclipsed conformation, because staggered conformation has torsional strain.
( D ) The eclipsed conformation of ethane is more stable than staggered conformation, because eclipsed conformation has no torsional strain.
