Why are many lakes in the Eastern Mediterranean very salty and full of minerals?
a. The earth around them has higher than normal levels of salt and minerals.
b. They have no outlets to the ocean, and the minerals have built up over time.
c. They lie below sea level.
d. The nearby Mediterranean Sea is extremely alkaline
"b. They have no outlets to the ocean, and the minerals have built up over time" is the best option from the list. For the salt to dissipate to "normal" ocean levels there needs to be consistent contact with at least one major, outside body of water.
