H3BO3 (aq) + H2O (l) leftharpoons [B(OH)4]- (aq) + H+ (aq)

Q. $H_{3} B O_{3}$ ionises in water as

$H_{3} B O_{3} (a q) ⇌ H^{+} (a q) + H_{2} B O_{3} (a q)$

$H_{3} B O_{3} (a q) ⇌ 2 H^{+} (a q) + H B O_{3}^{2 -}$ (aq)

$H_{3} B O_{3} (a q) ⇌ 3 H^{+} (a q) + B O_{3}^{3 -}$ (aq)

None of these

$H_{3} B O_{3} (a q) + H_{2} O (l) ⇌ [B (O H)_{4}]^{-} (a q) + H + (a q)$
