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 bidi. Madhu started rolling bidis at an early age and she enjoys it as it provides her the oppportunity to sit close to her mother and other women and listen to their 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 backpain. Madhu wants to restart her schooling.

Rolling bidi for long hours in the same posture may lead to which of the following?

Backache

The correct answer is Option (3) → Backache

The passage mentions that due to spending long hours in the same posture daily, Madhu suffers from back pain. This indicates that prolonged sitting and repetitive motions involved in bidi rolling can cause discomfort and strain on the back, leading to backache. Therefore, backache is the correct answer.
