4-can you mention the source?please
5-I think BANK was not there in question rather only BRICS organization'headquarter was asked.[/QUOTE]

BRIC was establised in 2009 and in 2010, with inclusion of South Africa, it became BRICS. It had no headquartters but in 2014 BRICS bank was established in Shanghai, China. In the question,most probably the examiner meant BRICS Bank. Although, bank was not mentioned.
