Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

The "World Bank" is Part of the "World Bank Group" which consists both the International Bank for Reconstruction and Development(IBRD), and the International Development Association (IDA). IBRD and IDA are collectively known as World Bank. But since the option only has "IBRD", we can choose it as answer as rest of them have separate objectives than the world bank. Hope that helps.
