Answer:
Ionic bonding: C
Covalent bonding: B
Metallic bonding: D
Pauli exclusion principle: A
Explanation:
All the electrons in 1 atom are characterized by a series of 4 numbers, known as quantum numbers. These numbers (n, l, ml, ms) describe the state of each electron (in which level, sublevel, orbital it is and its spin). For 2 electrons to coexist in the same atom they must differ in at least of these numbers. If they occupy the same level, sublevel and orbital, then they must have different (and opposite) spins. This is known as Pauli exclusion principle.
Also, to gain stability atoms can gain, lose or share electrons. In doing so they form bonds. There are 3 kinds of bonds:
- Ionic bonding: these are formed between metals and nonmetals. Metals tend to lose electrons and form cations (positive ions) and nonmetals tend to gain electrons and form anions (negative ions). Cations and anions attract each other due to <em>electrostatic forces</em> between <em>oppositely charged ions</em>.
- Covalent bonding: these are formed between nonmetals, which share pairs of electrons so as to reach the <em>electron configuration</em> of the closest noble gas (the most stable electron configuration).
- Metallic bonding: valence electrons are loose in metals, so they move together as a "sea of electrons", acting as <em>"glue"</em> of the remaining positive <em>cores</em> (electrons that are negative charges serve to attract the positive charges of the cores).

Holes in volcanic rocks illustrates a low pressure and rapid cooling environment(surface of the earth).
Explanation:
Holes in rocks are usually found in a special type of volcanic rock called pumice. The holes signifies a melt that has a lot of dissolved gases in them and they solidify rapid under surface temperature.
- Pockets of holes found in some rocks are as a result of trapped gases in cavities of a solidifying magma.
- The magma must erupt explosively so that the gases will not have enough time to escape.
- During an extrusive magma activity, the low pressure allows for dissolved gases to collects in cavities and magma cools rapidly around them due to the low surface temperature.
- The cavities left behind when the gases escape is the hole formed in volcanic rocks.
