`Ca_(2)B_(6)O_(11)+Na_(2)CO_(3) overset(Delta)rarr[X]+CaCO_(3)+NaBO_(2)` ( unbalanced equation) Incorrect choice for [X] is :

A

Structure of anion of crystalline [X] has one boron atom `sp^(3)` hybridised and other three boron atoms `sp^(2)` hybridised.

B

X on heating gives a compound which on reaction with hydrogen peroxide in alkaline medium yields a compound used as brighter in soaps.

C

It's aqueous solution is basic.

D

[X] +conc. `H_(2)SO_(4) rarr H_(3)BO_(3)+Na_(2)SO_(4)`
