Which of the following oils does not contain trans-fats?

Coconut oil is recognized for not containing trans fats, which are artificially created through a process called hydrogenation that solidifies liquid oils. Trans fats are known to increase the risk of heart disease and other health problems.

Among the listed oils, olive oil, soybean oil, and corn oil can potentially have varying levels of trans fats, particularly if they undergo hydrogenation to create a more solid form or shelf-stable product. However, unrefined and naturally extracted forms of these oils typically do not contain trans fats. Coconut oil remains a popular option for cooking and baking because it is a plant-based fat that remains solid at room temperature, is minimally processed, and retains its natural composition without the need for hydrogenation.
