Read the passage carefully and answer the following questions.

Madhu is a 15-year old school dropout. She stopped going to school after failing in class VIII. Her father, a tailor, expired last year. He was suffering from Tuberculosis. This made it necessary for the children and their mother to work. Her elder brother aged 17 years works in a grocery shop and the younger one aged 14 years is engaged in chocolate packaging. Madhu and her mother roll bidis. Madhu started rolling bidis at an early age and she enjoys it as it provides her the opportunity to sit close to her mother and other women and listen to them chat. She fills tobacco into the rolled tendu leaves. She spends most of her time in this activity apart from the time spent doing household chores. Due to long hours of sitting in the same posture daily, she suffers from backache. Madhu wants to restart her schooling.

Madhu's work can be understood as which type of work?

Informal work within informal sector

The correct answer is Option (4) → Informal work within informal sector

Madhu and her mother's bidi rolling activity does not have formal employment arrangements, and they are not officially registered as workers. Additionally, their work falls within the informal sector, as it involves unregulated and often low-paying activities conducted outside the framework of formal labor laws and regulations.
