Desertification extends beyond the expansion of existing deserts to include land degradation due to human activity in drylands.

The answer is D. Chordata.
There are three domains of life - Archaea, Bacteria, and
Eukarya. All organisms that belong to the domains Archaea or
Bacteria have cell walls. In the domain Eukarya, there are some groups

Chordata is phylum of the kingdom Animalia which belongs to the domain Eukarya. So, Chordata cannot be a domain.
