The most stable conformation of trans-1-tert-butyl-2-methylcyclohex ane is the one in which:

The most stable conformation of trans-1-tert-butyl-2-methylcyclohexane is the one in which both the tert-butyl group and the methyl group are located near the equatorial position. Trans conformation are usually stable at the equatorial position to avoid the bulkyl group ( the tert-butyl group and methyl group) be together to reduce the so called Steric hindrance.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
