Airbus is exploring three concepts for zero-emission commercial aircraft. Which of the following is one of their designs?

Airbus is actively researching and developing zero-emission commercial aircraft concepts, and one of the prominent designs features a turbofan configuration with a range exceeding 2,000 nautical miles. This type of design aligns with the industry's push toward more sustainable aviation technology, as turbofan engines are known to be efficient and potentially compatible with alternative fuels, such as hydrogen. These aircraft can aim for significant range capabilities while minimizing environmental impact, which is a critical goal for the future of aviation.

Other designs mentioned might not be as viable given current industry standards and passenger requirements. For example, a jet design with a range of 4,000 nautical miles, while ambitious, may pose challenges in terms of the weight and efficiency needed for a zero-emission solution. Similarly, a glider design with no seating capacity doesn't align with the commercial aircraft focus, which fundamentally requires a passenger carrying capability. An electric design that seats 300 passengers is interesting but may face hurdles in battery technology and weight capacity for such a large number of passengers, making it less practical at this time compared to the turbofan option.
