Final answer:
The Kermadec Trench is correctly identified as the Tonga Trench (Option D). While the Mariana Trench is the deepest part of the ocean and is near the Philippines, the question does not concern its depth or pressure calculations.
Step-by-step explanation:
The question asks which option correctly identifies the Kermadec Trench, another very deep place in the ocean. The correct answer is D) Tonga Trench. The Kermadec Trench and Tonga Trench are part of the same trench system in the South Pacific Ocean, and they are not the Mariana Trench, Puerto Rico Trench, or Sargasso Sea.
Regarding the additional information provided, the Mariana Trench is indeed the deepest part of the ocean and is located near the Philippines. The pressure at the bottom of the Mariana Trench can be calculated by using the formula P = ρgh, where ρ is the density of seawater, g is the acceleration due to gravity, and h is the depth of the water column above the point in question. Since this calculation involves physics principles, it could be classified under Physics when answering those parts of the question.
