Question

What is true of saturated fatty acid chains? They are more healthy that unsaturated fats. They contain only single covalent bonds. They are only made in leaf cells of green plants. They contain at least one double or triple bond.

Answer 1

"They contain at least one double or triple bond" is true of saturated fatty acid chains. This extra bond is why they are called "saturated", because they had less ability to take on other bonds.
