At the Gillette plant, consumer testers determined a can of Gillette Foamy (containing about 327 ml of
shave cream) fluffs up to 2675 ml when dispensed from the can. Assuming the can was dispensed at standard
atmospheric pressure of 101.3 kPa, what was the original pressure on the shave cream when it was
pressurized to fit inside the can?

the correct answer to this question is 2

the answer your looking for is c).

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
