Expert Solution

Marianas Trench: It is the deepest part of the oceans. This trench is about 11 km deep. It can swallow whole Mount Everest with over 2 km to spare.

(a)

Ocean depths are greater than the land heights. Therefore, the average depth of ocean basin below the sea level is greater than the average height of continents above the sea level. Therefore, the option (a) is not correct.

(b)Ocean depths are greater than the land heights. The average depth of ocean basin below the sea level is greater than the average height of continents above the sea level. Therefore, the option (b) is correct.

(c)

The average depth of ocean basin below the sea level is greater than the average height of continents above the sea level. Therefore, the option (c) is not correct.

(d)

The average depth of ocean basin below the sea level is greater than the average height of continents above the sea level. Tides do not make much change in the average depth of ocean basin below the sea level. Therefore, the option (d) is not correct.

Marianas Trench: It is the deepest part of the oceans.
