Solution

The correct option is B
Carbene

Explanation for correct options:
B. Carbene
Carbene has two unshared valence electrons with a neutral carbon atom.
Carbenes are neutral substances with just six valence electrons on the carbon atom.
They are highly reactive in nature.
“Carbenes are divalent compounds with two valence electrons distributed between two nonbonding orbitals and a carbon atom covalently bound to two other groups.”
Thus, “A neutral divalent carbon species obtained by the removal of two monovalent atoms from the same carbon is called a Carbene.”
Explanation for incorrect options
(A) Carbanion
A carbanion is a negatively charged species carrying a trivalent carbon atom.
An example of carbanion is ${CH}_{3}^{-}$ .
(C) Carbocation
A carbocation is an ion with a positively charged carbon atom.
An example of carbocation is $\overset{+}{C} H_{2} {CH}_{3}$ .
(D) Free radical
A free radical is an ion/molecule/species that contains at least one unshared pair of electrons.
An example of free radical is $NO ∙$ .
Hence, the correct option is B i.e. Carbene.
