Article 23 prohibits traffic in human beings and forced labour (begar). Article 24 prohibits the employment of children below the age of 14 in factories etc. - Children (1): Explicitly protected by Art 24 from child labour and also covered by Art 23 (trafficking, forced labour). - Women (2): Significant victims of human trafficking, which is prohibited by Art 23. - Tribals (3): Historically subjected to forced and bonded labour (begar), prohibited by Art 23. - Dalits (4): Historically subjected to forced and bonded labour (begar) and practices like manual scavenging, prohibited by Art 23. All four groups are beneficiaries. However, since option (1, 2, 3, and 4) is not available, there might be a specific grouping intended. Option C includes Children (specific Art 24), Women (major focus of trafficking under Art 23), and Tribals (major group affected by forced labour under Art 23). While excluding Dalits is questionable, this combination appears to cover the most explicitly or historically emphasized categories among the choices, assuming the question/options are not flawed.
