In which work is it wrong to employ a child below fourteen years?

Correct answer: Hazardous factory

The direct answer is A: employing a child below fourteen in a hazardous factory is wrong and constitutionally prohibited. The relevant principle is that children must not be employed in factories, mines, or other hazardous work. Such work can expose them to machines, chemicals, fire, injury, and loss of education, so it is treated as exploitation. Option A is correct because it combines the protected age group with dangerous employment. Option B, studying at home, is not employment and is not harmful labour. Option C, playing, is a normal activity and is not employment. Option D, drawing, is ordinarily a harmless creative activity and is not the hazardous employment described. The important distinction is between a child doing an ordinary safe activity and a child being employed in dangerous work. Read the words carefully: “below fourteen” and “hazardous factory” are the decisive clues. Do not select an option merely because it involves a child; select the one involving prohibited dangerous employment. Memory cue: under 14 plus hazardous workplace points to the constitutional ban on child labour in hazardous occupations.
