Option D:

1. The only ranking that is higher in the hierarchy than phylum, is the kingdom.

3. The kingdom is the highest category where various phyla are grouped together.

Two organisms of the same phyla can be from different families.

For example; Phylum Annelida has two different families- Palpata, Echiura.

Final answer: If two organisms are in the same phylum, they must also be in the same kingdom.
