Assuming that the mass m of the largest stone that can be moved by a flowing river depends upon the velocity v of the water, its density \[\rho \] and the acceleration due to gravity g. Then m is directly proportional to:

• A. \[{{\nu }^{3}}\]
• B. \[{{\nu }^{4}}\]
• C. \[{{\nu }^{5}}\]
• D. \[{{\nu }^{6}}\]
