Answer» RIGHT option is (b) Increase in mass due to internally cell division and increase in number due to replication are twin characteristic of growth

Easy explanation: Increase in mass due to internal division and increase in number of organisms are twin characteristics of growth. In non-living organisms increase in mass occurs due to accumulation whereas in living organisms it happens due to the proteins and CARBOHYDRATES that we INTAKE. Living organisms except plants GROW until certain period of their life and then stop growing. Growth is not a sufficient a characteristic to determine if an organism is living. Sometimes it’s possible that even mountains and sand dunes grow due to an accumulation of sand.
