The principal ingredients in sunscreens are usually aromatic molecules conjugated with carbonyl groups. This general structure allows the molecule to absorb high-energy ultraviolet rays and release the energy as lower-energy rays, thereby preventing the skin-damaging ultraviolet rays from reaching the skin.

The answer is c)\n\nProtonation of the double bond gives the more stable secondary carbonium ion, this reacts with Br- to give the product.\n\nIn the presence of peroxide the reaction goes through a radical mechanism to give the reverse selectivity

According to their website, they are using a narrow band UVB process. They state:\n\n"Narrow Band UVB virtually eliminates superfluous and harmful UV by emitting only wavelengths 311-312 nm. Clinical studies show the peak therapeutic effectiveness of UVB to be within the range of 295-313 nm, but wavelengths below 300 nm can cause erythema or severe burning and increase the risk of skin cancer. "\n\nHope this sets you mind at ease!

If 3-methylpentane undergoes reaction with Br2 with light present the product of the reaction will be 3-bromo-3-methylpentane.  The reason that the bromine will attach at the 3-carbon on the pentane chain is because the bromine will add to the most substituted carbon and the 3-carbon is the only tertiary carbon in the molecule and is therefore the most subsituted carbon.  Bromine is very selective for more substituted carbons so the major product will be 3-bromo-3-methylpentane.  \n\nIf you subject 3-bromo-3-methylpentane to Grignards reagent the magnesium will subsitute at the bromine position and will sandwich itself between the 3-carbon of the pentane backbone and the bromine atom.  The name of the final product will be 3-methyl-3-pentylmagnesium bromide.

It's pentanal, because it's a terminal carbonyl. It's certainly not pentanol, because otherwise you'd have a carbon missing 2 bonds, or a carbon missing 1 bond and an oxygen missing 1.
