\n– The Challenger expedition did indeed make the first recorded sounding of the trench in 1875.
\n– The dimensions of the trench are approximately 2550 km (1,580 miles) long and 69 km (43 miles) wide, making statement C correct.
\n– 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.
