The correct answer to the question is option 1: Indonesia. The Indian Navy recently launched a relief operation called Operation Gambhir in Indonesia. This was in response to the earthquake and tsunami that struck the island of Sulawesi in September 2018. The operation aimed to assist the Indonesian government in providing relief and support to the affected people. The Indian Navy deployed INS Sumitra, a naval offshore patrol vessel, to assist in the relief efforts. The ship carried essential supplies such as food, medicines, and blankets to the affected areas. It also provided medical assistance and conducted aerial surveys for damage assessment. The operation was a part of India`s ongoing efforts to strengthen bilateral ties and contribute to humanitarian assistance in the region.
