What is which country is at the centre of the earth?

There is no country at the center of the Earth. The center of the Earth is a molten iron-nickel core, which is about 6,371 kilometers (3,959 miles) below the Earth's surface. This core is surrounded by a layer of hot, dense rock called the mantle, followed by a thin crust where we live. The Earth's core plays a crucial role in generating the planet's magnetic field, which helps protect us from harmful solar radiation.
