Verified step by step guidance

Step 1: Begin by understanding the terminology related to fatty acids. Fatty acids are classified based on the number of double covalent bonds in their hydrocarbon chain.

Step 2: Define the key terms: Saturated fatty acids have no double bonds, monounsaturated fatty acids have one double bond, and polyunsaturated fatty acids have two or more double bonds. Trans fatty acids are a type of unsaturated fatty acid with a specific configuration of the double bond.

Step 3: Analyze the problem statement. It asks for the classification of a fatty acid that contains two or more double covalent bonds.

Step 4: Match the definition of polyunsaturated fatty acids to the description provided in the problem. Polyunsaturated fatty acids are characterized by having two or more double covalent bonds in their structure.

Step 5: Conclude that the correct answer is 'a polyunsaturated fatty acid,' as it aligns with the description of having two or more double covalent bonds.
