i. by water seeping through the ocean floor and welling up into the lake
Explanation:
Oceans the lowest unit of deposition of all continental materials. It is also known that all the water on land drains into the oceans. Oceans receives large volume of fresh water because they are down the gradient and base level of the continent.
It is near impossible for water from oceans to flow landward.
Lake Okeechobee in Florida will empty into the ocean at the Gulf of Mexico. For an exchange of water to occur between these two bodies of water, we must consider infiltration through the ocean floor into the land. Water can seep into pore spaces in form of salt water intrusion which can be carried into the lake body. This is the most reasonable way water from the Gulf of Mexico can move into the lake.
