Final answer:
The body stores energy for long-term use in lipids, making option C) Lipids the correct answer.
Step-by-step explanation:
Your body stores energy for long-term use predominantly in lipids, which are fats and oils, as they contain high energy bonds.
Carbohydrates are usually the body's preferred energy source for quick use because they are more easily broken down.
While proteins can also be utilized for energy, they mostly serve as building materials and are not a primary energy reservoir.
Nucleic acids, like DNA and RNA, are essential for storing and transmitting genetic information, not for long-term energy storage.
Looking at the options A) Carbohydrates B) Proteins C) Lipids D) Nucleic acids, the correct answer is C) Lipids.
