Answer:
I believe the statement which supports the idea that oaks are usually a hearty tree is:
C. One of the most majestic trees is the oak tree.
Step-by-step explanation:
We can reach the conclusion above if we work with definitions and synonyms.
"Hearty" means, among other things, large or great. The adjective "majestic" is used to refer to something that inspires admiration or respect due to its size, beauty, or power. As we can see, both "hearty" and "majestic" are used to refer to the size of something, which means they can work as synonyms. Therefore, the statement that supports the idea that oaks are usually a hearty tree should be:
C. One of the most majestic trees is the oak tree.
