I'm pretty certain the answer is 2) because fluorine is a diatomic gas meaning it travels with 2 molecules (simplified). It is a gas so molecules should also be spread out so the answer cannot be 3) or 4).
Hope this helps! :)
The pH of 0.20 M HF (Hydrofluoric acid) is 3.27. Whereas, [H₃O⁺] for the same is 6.8 X10 ⁻⁴
<h3>
What is Hydrofluoric acid?</h3>
A hydrogen fluoride and water solution is hydrofluoric acid. HF solutions are colorless, corrosive, and acidic. The majority of fluorine-containing chemicals are made using it; examples include the substance PTFE and the widely used psychiatric drug fluoxetine. Aluminum, plastics, electrical components, pharmaceuticals, high-octane fuel, fluorescent light bulbs, and refrigerants are all made with hydrogen fluoride. The production of refrigerants uses 60% of the hydrogen fluoride used in manufacturing. corrosive due to the acid's H+ ions and poisonous due to the fluoride ions F-, which can penetrate deeply, chelate calcium and magnesium, and thus upset biological balances due to the destruction of the skin's or an eye's outermost layer.

Concentration: mole=volume x M
Food labels can tell someone how nutrient-dense a food is. It can show calories, fat, and others. Hope that helps.
The amount of kinetic energy required for the molecules to break free of the intermolecular forced in the liquid is raised because the other ones don’t make sense
