Arrange the following statements about United Nations in ascending order.

E. Antonio Guterres became Ninth (9th) secretary-General of the UN

Choose the correct answer from the options given below:

A, B, D, C, E

The correct answer is Option 1 - A, B, D, C, E

The correct ascending order of the statements about the United Nations is:

A. In 1945 UN was established through the signing of the United Nations charter by 51 states - 1945

B. UN Security council membership was expanded from 11 to 15 - 1965

D. UN declared the US invasion of Iraq as an illegal act - 2004 (In September 2004, United Nations Secretary-General Kofi Annan declared the US invasion of Iraq to be illegal and "not in conformity with the UN Charter".)

C. Agreements to achieve the Millennium Development Goals (MDGs) in UN meeting - September 2005. (MDGs were adopted in 2000, but Agreements to achieve them was taken in UN meeting in 2005)

E. Antonio Guterres became Ninth (9th) secretary-General of the UN - 2017

Note: The statement D is not factually correct. The United Nations as a body never officially declared the invasion illegal. There was no formal resolution by the Security Council declaring it illegal. The UN Secretary-General Kofi Annan stated in 2004 that the invasion was “not in conformity with the UN Charter” and hence illegal.
