The correct option is D Type 001A
Chinas first domestically developed aircraft carrier Type-001A has recently started sea trials. The aim of trials is to demonstrate the reliability and capability of the ships propulsion systems. The 50,000-metric tonne vessel will become the countrys second aircraft carrier, and the first to be entirely built and designed inside of China, when it joins the navy before 2020. Few countries in the world have aircraft carriers. Besides India, the US, Russia, the UK, France, Italy, Thailand and China operate a total of 18 aircraft carriers.
