Consider the `M(OH)_(3)` formed by all the group 13 elements. The correct sequence of acidic strength of hydroxides `[M(OH)_(3)]` is-

A

`B(OH)_(3) lt AI(OH)_(3) gt Ga(OH)_(3) gt ln(OH)_(3) gt TI(OH)_(3)`

B

`B(OH)_(3) gt Tl(OH)_(3) gt Al(OH)_(3) gt ln(OH)_(3) gt Ga(OH)_(3)`

C

`Al(OH)_(3) gt Ga(OH)_(3) gt B(OH)_(3) gt ln(OH)_(3) gt Tl(OH)_(3)`

D

`B(OH)_(3) gt Al(OH)_(3) gt Ga(OH)_(3) gt ln(OH)_(3) gt Tl(OH)_(3)`
