A hydrogen bond is formed when a positively polarized hydrogen atom in one molecule is attracted to a highly electronegative atom in another molecule. In the example of water molecules, the negatively charged oxygen atom in one water molecule attracts the positively charged hydrogen atom in another water molecule. Oxygen atoms tend to steal electrons away from the hydrogen atoms within molecules. When this occurs within a water molecule, the electron loss creates a hydrogen atom with a partial positive charge, which is then attracted to a negatively charged oxygen atom in another water molecule.
The hydrogen bonds that form between water molecules cause them to stick together. This gives water a high boiling point temperature because a greater degree of heat energy is required to break the intermolecular hydrogen bonds. Many organic substances that are required to sustain life, such as nucleic acids and proteins, contain hydrogen bonds. Although these bonds are weaker than the internal ionic or covalent bonds existing between the atoms within molecules, the accumulated strength of hydrogen bonds within living organisms is highly significant and plays an important role in maintaining stability.

Answer:
The correct answer would be option D, Cigarette Smoke.
Explanation:
Air Pollution is simply the pollution in the Air. Air pollution consists of gases or solid particles. Air pollution can be indoor and out door. Outdoor pollution is caused by the chemical emissions, factory gases emission, dust, car emissions, etc. The indoor air pollution would be considered the pollution that is caused by the indoor sources, such as fuel burning, smoke generation, etc. So the source of indoor air pollution which is considered the greatest is Cigarette Smoke, as large amount of people smoke inside the facilities, increasing the air pollution.
C is the answer lol can u give me brainliest
