✓

Answer

Correct option: A.
Redox reaction
a
Cross cannizzaro reaction is an example of redox reaction. For example, in the crossed cannizaro reaction of benzaldehyde and formaldehyde, benzaldehyde is reduced to benzyl alcohol as no alpha hydrogen atom is present. Formaldehyde is oxidized to formic acid.
