– It is located in the Western Pacific Ocean, to the West of Mariana island
– The trench was first sounded during the Challenger expedition in 1875

– The dimensions of the trench are approximately 2550 km (1,580 miles) long and 69 km (43 miles) wide, making statement C correct.
– The maximum depth of the Challenger Deep in the Mariana Trench is over 10,994 meters (~11 km). Hydrostatic pressure increases by approximately 1 atm for every 10 meters of depth. At 11 km, the pressure is about 1100 atm, which is indeed over 1000 times standard atmospheric pressure at sea level, making statement D correct.
