Explanation:

The stark difference is Racism and Xenophobia is that racism is discrimination based on physical characteristics whereas xenophobia is discrimination based on the perception that someone is foreign or originating from another community or nation. 

• The word Xenophobia originates from the Greek word Xeno.
• Xenophobia and Racism are often overlapped.

Article 15, Article 16 and Article 29 of the Constitution of India prohibit discrimination on ground of “race”. 

• Section 153A of the Indian Penal Code (IPC) also refers to “race”.

Article 24 of the Indian Constitution deals with Prohibition of Child Labour.

• India also ratified the International Convention on the Elimination of All Forms of Racial Discrimination (ICERD) in 1968. 

Hence only statements 2&3 are correct.
