Explanation
Why Correct: Lord Ripon, Viceroy from 1880 to 1884, enacted the First Factory Act in 1881 to regulate labor conditions, including restricting child employment and setting maximum working hours.
Distractor Analysis: Lord Curzon partitioned Bengal in 1905 and established the Archaeological Survey of India. Lord Wellesley expanded British control through the Subsidiary Alliance system in the early 1800s. Lord Cornwallis introduced the Permanent Settlement of land revenue in 1793.
Takeaway: The First Factory Act applied initially to factories with 100+ workers, banned employment of children under 7, and limited those aged 7-12 to 9 hours daily, laying groundwork for subsequent labor laws.
