Final answer:

The type of energy transferred to your body when basking in sunlight is heat transfer. Eating food transfers internal energy, and riding an elevator to a higher floor involves doing work. The correct classifications are heat transfer for sunlight, internal energy for eating food, and doing work for riding an elevator.

Step-by-step explanation:

When identifying the type of energy transfer to your body in various activities, it's important to understand the concepts of heat transfer, doing work, and internal energy. Here's the correct classification for each scenario:

  • (a) Basking in sunlight: This is an example of heat transfer. The sunlight transfers energy to your body in the form of heat, which raises your body's temperature.
  • (b) Eating food: When you eat food, your body is effectively receiving internal energy. The calories from the food are a source of potential energy that your body can convert into kinetic energy or use for bodily functions.
  • (c) Riding an elevator to a higher floor: This is an example of doing work. The elevator does work on your body by applying a force through a distance, thus increasing your gravitational potential energy.

The correct answer from the options provided would therefore be (d): (a) Heat transfer; (b) Internal energy; (c) Doing work.
