Identify the incorrect pair from the following:

Explain the nature of boric acid $(H_3BO_3)$ as a Lewis acid in water. The structure of $H_3BO_3$ is given below:
$H-O-B(OH)_2$

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$ : Boric acid is a weak acid.
Reason $R$ : Boric acid is not able to release $H^{+}$ ion on its own. It receives $OH^{-}$ ion from water and releases $H^{+}$ ion.
In the light of the above statements,choose the most appropriate answer from the options given below.

Given below are the statements about diborane.
$(a)$ Diborane is prepared by the oxidation of $NaBH_{4}$ with $I_{2}$.
$(b)$ Each boron atom is in $sp^{2}$ hybridized state.
$(c)$ Diborane has one bridged $3$ centre$-2-$electron bond.
$(d)$ Diborane is a planar molecule.
The option with correct statement$(s)$ is :

Explain what happens when boric acid is heated.

$STATEMENT-1$: In water,orthoboric acid behaves as a weak monobasic acid. because
$STATEMENT-2$: In water,orthoboric acid acts as a proton donor.
