The correct answer is (a).
The Hicklin Test is a test used to determine whether or not material is obscene. It was developed in the 1868 case of Regina v. Hicklin, and it holds that material is obscene if it tends to deprave and corrupt those whose minds are open to such immoral influences.
The Hicklin Test has been criticized for being too broad and for failing to take into account the context in which material is published. However, it remains the standard test for obscenity in many countries, including India.
The other options are incorrect because they are not related to the Hicklin Test. Defamation is a tort that protects a person’s reputation from false statements. Integrity of India is a fundamental principle of the Indian Constitution.
