Why C is correct
46 CFR §56.50-65(a) requires all discharge piping from fuel oil service pumps to burners to be seamless steel with a thickness of at least Schedule 80. Schedule 40 and 60 are lighter walls that do not meet this requirement; Schedule 160 exceeds the minimum but is not the stated standard.
