Inde l' or d' or none

Bonjour Divya !

I'd say that you first example is incorrect, as in French you will always use the definite article (here l') with countries in such sentences.

So I would say: Informations générales sur l'Inde

See our related lesson:

You will use d'Inde when indicating a provenance (from India) :
des épices d'Inde
Je viens d'Inde. 

I hope that's helpful!
Bonne journée !
