The correct answer is Option 1: By providing genetic and bio-diversity

Environment performs four functions: supplies resources, assimilates wastes, sustains life by providing genetic and bio diversity and provides aesthetic services.

The environment supports the sustenance of life by providing genetic and biological diversity, which is crucial for the resilience and adaptability of ecosystems. This diversity ensures the availability of a wide range of species and genetic materials that contribute to the health and stability of ecosystems, ultimately supporting all forms of life on Earth.
