Explanation:

Solve  by elimination.  If you notice, both 3 and 4 are written as pre-independence acts, which isn’t  the case. It is actually - Payment of Bonus Act 1965 and Equal Remuneration Act 1976. Both progressive measures were passed post-independence and could not have been expected in a colonial setup. Statement 2: It was passed right after independence to ensure social justice, and the year of passing of this act should be common knowledge to you. It was “Minimum Wages Act 1948”.  The bill seeks to amend the laws relating to wages and bonus which  also seeks to empower the Centre to fix a “universal minimum wage” aimed to benefit over 40 crore unorganized sector workers.

• The bill seeks to amalgamate four laws — Payment of Wages Act 1936, Minimum Wages Act 1948, Payment of Bonus Act 1965 and Equal Remuneration Act 1976.
• The Code provides for the government to determine the minimum wages every five years using factors like skills required for the job, arduousness of work, geographical location of work place and other aspects.
