While researching a topic, a student has taken the following notes:

• A river's stream length is the length of a line that follows along the river path.
• A river's valley length is the length of a straight line drawn from the beginning of the river to the end.
• The river's curviness, or sinuosity, is the ratio of the river's stream length to its valley length.
• Low-sinuosity rivers have a stream length 1-1.5 times longer than their valley length, and high-sinuosity rivers have a stream length 1.5 or more times longer than their valley length.
• The Mississippi River in the United States has high sinuosity.
• The Neales River in Australia has low sinuosity.
The student wants to compare the curviness of the two rivers. Which choice most effectively uses relevant information from the notes to accomplish this goal?
The high-sinuosity Neales River in Australia is curvier than the low-sinuosity Mississippi River in the United States.
A
In both the Mississippi and the Neales rivers, curviness is determined by comparing stream length to valley length.
B
By comparing the stream lengths of the Mississippi and Neales rivers to their valley lengths, one can calculate their curviness, or sinuosity.
C
The Mississippi River's ratio of stream length to valley length, also known as sinuosity, is greater than that of the Neales River.
D
