Answer: (B)

Verified step by step guidance

1. Step 1: Understand the relationship between calories and grams of lipids. Lipids provide 9 Kcal per gram, which is a standard value in nutrition science.
2. Step 2: Use the formula to calculate grams of lipids: \( \text{grams of lipids} = \frac{\text{calories from lipids}}{\text{calories per gram of lipids}} \).
3. Step 3: Substitute the given values into the formula. Briana consumed 180 Kcal of lipids, and lipids provide 9 Kcal per gram. The formula becomes \( \text{grams of lipids} = \frac{180}{9} \).
4. Step 4: Perform the division to determine the grams of lipids consumed. This step involves dividing 180 by 9.
5. Step 5: Interpret the result to confirm the grams of lipids consumed. Ensure the value aligns with the nutritional context provided in the problem.
