Disclosure of identity of victim of rape is punishable in Indian Penal Code under Section :

Section 228
Section 228A
Section 229
Section 229A

The correct answer is (b), Section 228A of the Indian Penal Code.

Section 228A of the Indian Penal Code states that whoever publishes the name or any matter which may make known the identity of the victim of rape shall be punished with imprisonment of either description for a term which may extend to two years, or with fine, or with both.

The section was inserted in the Indian Penal Code by the Criminal Law (Amendment) Act, 2013. The amendment was made in response to the increasing number of cases of rape and sexual assault in India. The section was aimed at protecting the identity of the victims of rape and sexual assault, and to prevent them from being further traumatized by the disclosure of their identity.

The section has been criticized by some for being too broad and for potentially infringing on the right to freedom of speech. However, the section has also been praised for its effectiveness in protecting the identity of rape victims.

The other options are incorrect. Section 228 of the Indian Penal Code deals with defamation. Section 229 deals with wrongful confinement. Section 229A deals with causing hurt by means of poison, acid, etc.
