Which of these is a twin-engined, tandem rotor, heavy-lift helicopter?

The Boeing CH-47 Chinook is an American twin-engined, tandem rotor, heavy-lift helicopter developed by American rotorcraft company Vertol and manufactured by Boeing Vertol (later renamed Boeing Helicopter and now named Boeing Rotorcraft Systems). The CH-47 is among the heaviest lifting of Western helicopters. Its name, Chinook, is from the Native American Chinook people of Washington state.

The Chinook possesses several means of loading various cargoes, including multiple doors across the fuselage, a wide loading ramp located at the rear of the fuselage and a total of three external ventral cargo hooks to carry underslung loads. Capable of a top speed of 170 knots (200 mph; 310 km/h), upon its introduction to service in 1962, the helicopter was considerably faster than contemporary 1960s utility helicopters and attack helicopters, and is still one of the fastest helicopters in the US inventory. Improved and more powerful versions of the Chinook have also been developed since its introduction,
