Answer: D — Tamil
Tamil is included in the Eighth Schedule of the Indian Constitution as one of the 22 Scheduled Languages. Bhojpuri, Magadhi, and Rajasthani are grouped under 'Hindi' and are not separately listed in the Eighth Schedule.

The passage explicitly lists all 22 Scheduled Languages in a table, and Tamil (5.70% speakers) appears in it. The passage also states that Bhojpuri, Magadhi, and Rajasthani are "grouped together under 'Hindi'" — meaning they are not independent Scheduled Languages. This is a direct fact-recall question; just remember the table lists Tamil but not the other three options.
