option b is ncorrect because sex hormones is ok but genetics do play a role but arenot responsible totally for the onset

option c is brain chemicals and genetics both have a role but they need signals from others and cannot be called responsible for the onset of the puberty

option d is CORRECT because gonads release signals and then sex hormones are released for the onset of puberty.
