Question Explanation :

The question checks whether both statements about the rotational conformations of ethane are true and if the second one correctly explains the first.

Concept: Conformational Isomerism, potential energy barrier

Solution:

At room temperature, staggered and eclipsed forms of ethane cannot be separated. This is because they have a very small energy barrier between them (approximately 12.6 kJ/mol), which is easily overcome by the available thermal energy, causing them to rapidly inter convert.
