Final answer:
By subtracting the depth of the Brazil Basin from the Philippine Trench, we determine that the Philippine Trench is 3.857 kilometers deeper.
Step-by-step explanation:
To find out how much deeper the Philippine Trench is than the Brazil Basin, you need to subtract the depth of the Brazil Basin from the depth of the Philippine Trench.
Depth of the Philippine Trench = 10.047 km
Depth of the Brazil Basin = 6.119 km
Difference in depth = Depth of Philippine Trench - Depth of Brazil Basin
Difference in depth = 10.047 km - 6.119 km
Difference in depth = 3.857 km
Therefore, the Philippine Trench is option D.3.857 kilometers deeper than the Brazil Basin.
