Among the following statements pick the statement that best describes a living thing

The correct option is: Living organisms grow endlessly throughout their life.

Explanation:
Growth is one of the most fundamental and defining characteristics of living systems, representing an irreversible, permanent increase in size, mass, or volume of an organism or its parts.
Unlike non-living things, which can only grow externally by the accumulation of material on their outer surface, living organisms grow from within (intrinsic growth). This intrinsic growth is driven by continuous metabolic activities, cell division (mitosis), and cell enlargement, allowing living organisms to develop and maintain their structures throughout their life cycle.
