Which of the following statements is true with regard to the J-10 lighter aircraft, ?

The Chengdu J-10 (Jian-10) is a multi-role, single-engine fighter aircraft developed by the Chengdu Aircraft Industry Corporation (CAC) for the People's Liberation Army Air Force (PLAAF) of China [t3][t4]. Known in the West as the 'Vigorous Dragon', it is classified as a fourth-generation (or next-generation relative to its predecessors) tactical fighter designed for air superiority and multi-role missions [t1][t6]. While it utilizes Russian-made AL-31FN engines and reportedly drew design inspiration from the cancelled Israeli Lavi project, it is fundamentally a Chinese indigenous program [t3][t6]. It is not a version of the Russian Su-30MKI, which is a twin-engine heavy fighter [t2][t5]. Although Pakistan operates the export variant (J-10CE), the aircraft is of Chinese national origin rather than being a Pakistani indigenous development [t4][t5].
