The guidelines issued by the Supreme Court in the Vishaka Case specifically address the issue of sexual harassment in the workplace. This means that option 3, "sexual harassment at the workplace," is the correct answer.

The Vishaka Case was a landmark case in India that dealt with the issue of sexual harassment faced by women in the workplace. In 1997, the Supreme Court of India issued guidelines known as the Vishaka guidelines to prevent and prohibit sexual harassment at the workplace.

These guidelines lay down the definition of sexual harassment, guidelines for prevention, and a framework for redressal of complaints. They establish the responsibility of employers to create a safe and secure working environment, including adopting measures such as education and training programs, setting up complaint committees, and conducting impartial inquiries.

While options 1, 2, and 4 may be related to issues faced by women, the specific guidelines issued in the Vishaka Case focus solely on sexual harassment in the workplace. Therefore, they are not the correct answers.
