ANSWER i believe it's A. wax, which is made up of atoms that share electrons equally
For substance to be soluble in other substance, both substances must be either polar or non-polar. Wax/paraffin wax is non-polar and hence it's insoluble in water. Soap is polar as well non-polar hence it is slightly soluble in water.Salt is polar molecule hence highly soluble from all of the above. So option A.) wax, which is made up of atoms that share electrons equally is correct. Hope this helps!
