Answer 2

Explanation:

French India, formally the Établissements français dans l'Inde[a] (French Settlements in India), was a French colony comprising geographically separate enclaves on the Indian subcontinent. The possessions were originally acquired by the French East India Company beginning in the second half of the 17th century, and were de facto incorporated into the Republic of India in 1950 and 1954. The French establishments included Pondichéry, Karikal, Yanaon (Andhra Pradesh) on the Coromandel Coast and Mahé on the Malabar Coast and Chandernagor in Bengal. French India also included several loges ("lodges", subsidiary trading stations) in other towns, but after 1816, the loges had little commercial importance and the towns to which they were attached came under British administration.
