Natural selection acts only on phenotype. Mutation acts on genotype.

N.S. works on the phenotype, obviously, because that is what you are.
But, the phenotype is a result of a particular genotype, and if the phenotype is selected against, then that organism dies, taking its shonky genes with it.
If the phenotype is good, then that organism survives, breeds and passes on its good genes.

Selection acts on genetic varitation, while evolution acts on phenotypic variation.

both because natural selection influences your genes (genotype) which can influence the way you look (phenotype) such as hair color, height, etc.

Both, but phenotype more directly, and genotype more indirectly.
