Answer #1

Skin is slightly acidic due to secretion of sebum made up of fatty acids and due to secretion of sweat.

so, skin will be hypertonic when sweating is going on because sweat contains extra salts exceted from the budy surface.

the lower layer of the skin contains extracellular fluiud, which contains large noumber of macrophages flowing in this fluid, which help to kill the invading pathogens or microorganisma acting as first line of defence.

the skin is nutritionally deficient as the upper layers of the skin are made up of sead keratinized cells.

so, choice number 1, 3, 4, and 5 need to be overcome in order to colonize skin by the microbs.
