NBS is used to add Br at allylic position means at the carbon next to the C=C bond. In the given compound we have two allylic positions. one in methyl and another in propyl. This reaction takes via free radical mechanism. Propyl gives 2 degree free radical where as methyl gives 1 degree free radical. we know that 2 degree free radicals more stable than 1 degree.
