The velocity of water wave `v` may depend on their wavelength `lambda`, the density of water `rho` and the acceleration due to gravity `g`. The method of dimensions gives the relation between these quantities as
A. `v^(2) prop lamda g^(-)rho^(-1)`
B. `v^(2) prop glamda rho`
C. `v^(2)prop g lamda`
D. `v^(2) prop g^(-1) lamda^(-3)`
