The correct answer is: B. law of drainage composition
The law of drainage composition states that the mean basin area of successive ordered streams formed a linear relationship when graphed. This means that the larger the stream, the larger the area of its drainage basin. This law is based on the idea that streams are arranged in a hierarchical system, with smaller streams flowing into larger streams. The law of drainage composition can be used to estimate the size of a drainage basin from the size of its largest stream.
A. Morph metric analysis is a technique used to measure the shape of a drainage basin. It involves measuring the length, width, and slope of the basin, as well as the area of the basin.
C. Law of basin areas is a law that states that the area of a drainage basin is proportional to the square of the length of its longest stream. This law is based on the idea that the longer a stream, the larger its drainage basin.
D. None of the above is a correct answer.
