Hello. This question is incomplete. The full question is:
"Which of the following is not an ocean resource
a- sand b- common table salt c- natural gas d- silver"
Answer:
d- silver
Step-by-step explanation:
Silver is not an oceanic resource, but a mineral, a metal, a chemical element that can be found on the Earth's surface. As silver is a mineral, we cannot call it an oceanic resource, but rather a mineral resource.
A mineral resource is an inorganic substance, such as silver. There are other mineral resources such as iron, aluminum, manganese, sulfur, among others.
