Answer 1

The correct answer is:

(a) True

Castor oil is indeed compounded with heavy mineral oils to make extreme pressure lubricants. Castor oil, with its high natural lubricity, is often used in combination with heavier oils to enhance the performance of lubricants in high-stress or extreme pressure environments, such as those found in machinery and engine components.
