Which of the following intermediate has complete octet?

Solution
The correct option is C Carbanion
A carbanion has a negatively charged, trivalent
carbon atom that has eight electrons in its valence shell.
bond
pair shares two electrons between the bonding atoms and lone pair consists of two
unshared electrons.
So totally we have 6 shared electrons and 2
unshared electrons around the carbanion
In contrast to carbocations and carbon radicals,
a carbanion is destabilized by electron-donating groups bonded to the anionic center
because the center already has an octet of electrons.
