For gaseous state, if most probable speed is denoted by `C^(**)` average speed by `barC` and root square speed by `C`, then for a large number of molecules, the ratios of these speeds are
A. `C^(**):barC:C=1.128 : 1. 225 : 1`
B. `C^(**):barC:C=1:1. 128:1.225`
C. `C^(**):barC:C=1:1.125:1.128`
D. `C^(**):barC:C=1.225:1.128.1`
