Solution

The correct option is A nucleophilic attack, transfer of $H^{-}$ and transfer of $H^{+}$

The Cannizzaro reaction is as:
$H C H O + H C H O K O H (50 %) - ------ \to C H_{3} O H m e t h y l a l c o h o l + H C O O^{-} K^{+} a c e t a t e$

The mechanism of Cannizzaro reaction is as:

Step I: Attack of nucleophile $O H^{-}$ to the carbonyl carbon

Step II: The transfer of hydride ion from anion (I) to the second molecule of aldehyde and finally rapid transfer of proton takes place.

Option A is correct.
