Missy and Mu'tamid are looking at two trees growing in the back courtyard of their high school. Missy says that the first tree has a larger basal area because its roots extend much further than the second tree. Mu'tamid disagrees, saying that the second tree has a larger basal area because its trunk is larger. Who is correct?

A. Missy, because the roots of the first tree are most likely larger than the width of the trunk of the second tree.
B. Missy, when measuring basal area, the size of the roots is measured but the trunk size is not considered.
C. Mu'tamid, because the trunk is most likely larger than the width of the roots of the first tree.
D. Mu'tamid, when measuring basal area, the trunk is measured and the size of the roots is not considered.
