Measured in joules is it thermal energy or temperature

Thermal energy

Explanation:

Temperature is measured in kelvin (For SI metric units).

Energy is always measured in joules (For SI metric units).

Celsius (°C), Fahrenheit (°F), and Kelvin (K) are three different units usually used to measure temperature in daily life situations. Joules is the SI unit of work or energy. Temperature and heat energy are related, but they are not the same.

  long weird answer but i hope this works

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.
