- ADharwars - Aravallis - Vindhyans - Cuddapahs
- BAravallis - Dharwars - Cuddapahs - Vindhyans
- CVindhyans - Dharwars - Aravallis - Cuddapahs
- DCuddapahs - Vindhyans - Dharwars - Aravallis
Explanation
The Aravallis are the oldest (Archaean), followed by the Dharwars, then the Cuddapahs, and finally the Vindhyans (Proterozoic), which is the correct oldest-to-youngest order. This matches the standard geological succession of peninsular India. Hence option (B) is correct.
