Ionic conductances of hydrated `M^(+)` ions are in the order-

Options

A. `Li^(+)(aq) gt Na^(+)(aq) gt K^(+) (aq) gt Rb^(+)(aq) gt Cs^(+)(aq)`
B. `Li^(+)(aq) gt Na^(+)(aq) lt K^(+)(aq) lt Rb^(+) (aq) lt Cs^(+)(aq)`
C. `Li^(+)(aq) gt Na^(+)(aq) gt K^(+)(aq) gt Rb^(+)(aq) lt Cs^(+)(aq)`
D. `Li^(+)(aq) lt Na^(+)(aq) lt K^(+)(aq) lt Rb^(+)(aq) lt Cs^(+)(aq)`

Answer
