in generally atomic mass of elements is increases, with atomic number increases.
in groups/columns top to bottom atomic number of elements increases. so atomic mass increases. 1 group/family to 18 group/family have some characteristic properties, in that atomic mass also one property, that is increases from top to bottom.
in periods/Rows left to right atomic number increase, so atomic mass increases. in all 7 periods atomic number left to right increases them atomic mass increase.
so given all are true. answer e.
