Answer 1

Hint: The country which was recently added to the UN became the 193rd member of the UN. The country had recently become independent.

Complete answer: South Sudan became independent from the rest of Sudan as a result of the January 2011 referendum. The referendum was held under the terms of the 2005 Comprehensive Peace Agreement (CPA).
The CPA ended the decades-long civil war between the North and the South.
South Sudan became the latest and the 193rd country to join the United Nations. It became a member in 2011.
Option B - Kosovo - Kosovo has not achieved full member status at the United Nations. Kosovo unilaterally declared independence from Serbia.
Option C - Palau - The United Nations Security Council unanimously recommended to the UN General Assembly to admit the Republic of Palau into the UN in 1994.
Option D - Eritrea - Eritrea joined the UN as an official member on 28th May 1993. It gained independence after 30 years of struggle against Ethiopia.
Therefore the correct answer is option A.
