Fatty Acid Statements Evaluation Steps:

• Identify the number of provided statements about fatty acids.
• Evaluate each statement for accuracy based on biochemical definitions.
• Count the correct statements: three align with established facts on structure, function, and properties.
• Confirm the total against multiple-choice options.

Why C is correct:

• Three statements match core fatty acid principles, such as being carboxylic acids with hydrocarbon chains and roles in energy storage.

Why the others are wrong:

• A: Underestimates; only one correct ignores the additional two valid statements.
• B: Still low; misses the third accurate statement on saturation or essentiality.
• D: Overestimates; one statement is incorrect, likely on misclassifying a property.

Final answer: C
