Which country has gifted a pair of Giant Aldabra tortoise to India as a…

Concept: Nations sometimes gift a native or iconic wildlife species to another country purely as a goodwill gesture in bilateral diplomacy — a soft-power exchange (comparable to “panda diplomacy”) that is documented through official state-visit records rather than a trade or treaty instrument.

Application: In June 2018, the President of Seychelles visited India and presented a pair of Giant Aldabra tortoises to the Nehru Zoological Park in Hyderabad. Seychelles is the natural home of this species — the Aldabra Atoll, part of Seychelles’ outer islands, is the tortoise’s native range — and the gift was recorded by India’s Ministry of External Affairs as a goodwill gesture reinforcing India–Seychelles bilateral and conservation ties.

Cross-check — why the other offered countries do not fit:

• Indonesia is known for the Komodo dragon and Sumatran/Bornean biodiversity; the Aldabra tortoise's native range lies outside the Indonesian archipelago, and no such diplomatic gift to India is on record.

• Malaysia's notable wildlife-diplomacy ties center on species like the Malayan tiger; there is no record of Malaysia gifting Giant Aldabra tortoises to India.

• Thailand is recognised for elephant-conservation partnerships, not for the Aldabra tortoise, and carries no record of this particular gift.

Since only one country's natural habitat and official 2018 state-visit record match the gift described, the answer is confirmed as Seychelles.
