C- unlike oak roots, maple roots often invade water lines.

To compare an oak tree with a maple tree and determine the correct statement, we can analyze each option:

A. Oak is often used to make ships, while maple is often used for furniture.
To verify this statement, we can research the common uses of oak and maple wood. We can look up information on different wood types and their specific applications, such as shipbuilding and furniture making. By comparing oak and maple, we can conclude that this statement is incorrect, as oak is indeed often used for furniture construction as well.

B. Both maple and oak trees lose their leaves in the fall.
To validate this statement, we can observe maple and oak trees during the autumn season. We will notice that both types of trees go through the process of losing their leaves. Therefore, this statement is correct.

C. Acorns are good to eat, while maple seeds aren't.
To confirm or refute this statement, we can consult reliable sources on the edibility of acorns and maple seeds. By examining information about these two types of seeds, we can determine that while acorns are edible after proper preparation, maple seeds are not usually consumed by humans. Therefore, this statement is correct.

D. Unlike oak roots, maple roots often invade water lines.
To assess this statement's accuracy, we can search for information regarding the root systems of oak and maple trees and their potential interaction with water lines. By examining reputable sources, specifically those discussing trees' root behavior, we can conclude that while tree roots can impact water lines, there is no evidence suggesting maple roots invade them more frequently than oak roots. Consequently, this statement is incorrect.

Therefore, based on the explanations provided, the correct statement would be:

B. Both maple and oak trees lose their leaves in the fall.
