Hi there,

This is dimensional analysis, typically used in the sciences to convert between units. Familiarize yourself with the SI prefixes, such as kilo, milli, centi, etc. as these will be very useful later on to know their x10 power memorized.

thanks,

where are the choice options?

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.

if it's not useful, feel free to report for mistake in answer.
