Answer:
The duplication of a cluster of four Hox genes is equally likely as the duplication of a single Hox gene.

In biology the best hypothesis is the one that requires the fewest evolutionary changes.
Since three independent duplications of an individual Hox gene is in evolutionary terms, more complex than a single duplication or a cluster, then that hypothesis would be the most parsimonious.
