D. The oak tree population would stay the same.

Explanation:

Commensalism is a type of symbiotic association in which one organism gets benefit and the other is unharm. There is a commensalism relationship between blue-gray gnatcatchers and oak tree. Blue-gray gnatcatchers get benefit while oak tree get neither benefit nor harm. So if the population of blue-gray gnatcatchers decreases, there is no effect on oak tree.
