The correct answer is (d). China is constructing the One Belt One Road (OBOR) initiative. OBOR is a development strategy launched by Chinese President Xi Jinping in 2013. It aims to connect Asia with Europe and Africa through a network of land and sea trade routes. The initiative is also known as the Belt and Road Initiative (BRI).
India (a) is not constructing OBOR. Pakistan (b) is a part of OBOR, but it is not the country that is constructing it. Bangladesh (c) is not a part of OBOR.
OBOR is a massive undertaking that will cost an estimated $1 trillion. It is expected to have a significant impact on the global economy. The initiative has been praised by some for its potential to boost trade and investment. However, it has also been criticized by others for its potential to increase China’s influence in the region.
