I believe it is D as you are hearing the copper tube
C) Lower,
They're lower because molecular solids form IMF's such as Dipole-Dipole and H-Bonds, while Ionic bonds are much more powerful.
Answer:
A. Polar regions receive less solar energy and heat per unit area than tropical regions.
Explanation:
The sun is lower in the sky the farther away from the equator you go (at higher latitudes), so the solar energy is less direct. Climate in areas with less direct solar input tends to be generally cooler.

What is Electronic Configuration?
The arrangement of an atom's or molecule's (or other physical structure's) electrons in their atomic or molecular orbitals is known as the electron configuration in atomic physics as well as quantum chemistry. For instance, the neon atom's electron configuration is 1s2 2s2 2p6, which means that 1, 2 and 6 electrons, respectively, are present in each of the 1s, 2s, and 2p subshells. According to electronic configurations, each electron moves independently within an orbital while being surrounded by an average field produced by all other orbitals. Slater determinants as well as configuration state functions are used to mathematically describe configurations.

In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure, that occurs naturally in pure form.
hope this helps
