Final answer:
Ingredients like hydrogenated vegetable oil and shortening indicate the presence of trans fatty acids in a product, which can increase 'bad' LDL cholesterol, unlike liquid corn oil.
Step-by-step explanation:
Words on an ingredient list that would alert you to the presence of trans fatty acids in the product are "hydrogenated vegetable oil" and "shortening." Both of these indicate that the oils have undergone partial hydrogenation, a process that converts some of the natural cis double bonds into trans double bonds, thus creating trans fatty acids. These trans fats are associated with increased levels of low-density lipoprotein (LDL), commonly known as 'bad' cholesterol. On the other hand, "liquid corn oil" generally would not contain trans fats as it is typically not hydrogenated. Therefore, the correct answer to the question is 'e,' hydrogenated vegetable oil and shortening, but not liquid corn oil.
