Answer 1

The correct answer is:

(a) True

Fatty oils from animal and vegetable origin, such as lard oil or rapeseed oil, are sometimes used alone, but they are often mixed with mineral oils to enhance their properties. These oils provide natural lubrication qualities and can improve the performance of lubricants, especially in terms of their ability to handle higher temperatures and pressures.
