What does the doctor recommend for people with high blood cholesterol?

The correct answer is Option (4) - Vegetable Oil

Ghee, butter, red meat and vanaspati are rich sources of saturated fats. A patient with high blood cholesterol is suggested to consume unsaturated fats as vegetable oils.

Ghee : It's common in Indian subcontinent cuisine, Middle Eastern cuisine, traditional medicine, and religious rites.

Vegetable oil: Oil derived from a variety of fruits, seeds, grains, and nuts is known as vegetable oil (all considered vegetables for this purpose). Canola, coconut, corn, cottonseed, olive, palm, palm-kernel, peanut, safflower, soybean, and sunflower oils are the most common.

Dalda: Dalda is a brand of vanaspati, which is made from hydrogenated vegetable oil, most commonly palm oil (as you see a palm tree in the company logo). It contains a lot of trans fat, therefore it's best to stay away from it.
