Consider the following reactions:
$(a) \ B_2H_6 + 6H_2O \to 2H_3BO_3 + 6H_2$
$(b) \ B_2H_6 + 6CH_3OH \to 2B(OCH_3)_3 + 6H_2$
$(c) \ B_2H_6 + 3Cl_2 \to 2BCl_3 + 6HCl$
$(d) \ B_2H_6 + 6CH_3COOH \to 2B(OCOCH_3)_3 + 6H_2$
Identify the incorrect statement about the product$(s)$.

• A
  $H_2$ is a common product in all the reactions.
• B
  Reaction $(d)$ forms an alkane.
• C
  The product of reaction $(a)$ has $H$-bonds in the solid state.
• D
  One of the products of reaction $(c)$ is used for dissolving noble metals along with conc. $HNO_3$.
