What is the theme of Uttaradhyayana Sutta?

The correct answer is Option 3 - It describes how a queen named Kamlavati tried to persuade her husband to renounce the world.

Similarly to how the Buddha's teachings were preserved by his followers, the teachings of Mahavira were also meticulously recorded by his disciples. These accounts often took the form of engaging stories, making them accessible and appealing to ordinary people. One such example can be found in the Prakrit text known as the Uttaradhyayana Sutta. This story narrates the endeavors of Queen Kamalavati as she attempts to convince her husband to embrace a life of renunciation.
