Final answer:
Saturated fats are solid at room temperature and can elevate LDL ('bad cholesterol') levels in the blood. They do not lower LDL cholesterol and aren't liquid at room temperature. They also don't spoil easily.
Step-by-step explanation:
The statements a. Solid at room temperature and d. Elevates LDL blood cholesterol are true about saturated fats. Saturated fats are typically solid at room temperature because they are closely packed together due to the absence of double bonds in their structure. They are also known to elevate LDL (low-density lipoprotein, usually referred to as 'bad cholesterol') levels in the blood, which can lead to heart disease over time if consumed excessively. Statement b is incorrect as fats, including saturated fats, do not spoil easily due to their chemical nature. Statement e is incorrect because saturated fats are solid, not liquid, at room temperature. Lastly, they do not lower LDL blood cholesterol, making statement c incorrect.
