Step 1: Biological classification arranges organisms into hierarchical categories based on similarities.
Step 2: The correct descending order from highest to lowest is:
\[
\text{Kingdom}>\text{Phylum}>\text{Class}>\text{Order}>\text{Family}>\text{Genus}>\text{Species}.
\]
Step 3: From the given categories, the correct order is:
\[
\text{Phylum}>\text{Class}>\text{Order}>\text{Family}>\text{Genus}.
\]
Hence, option (d) is correct.
