C. Can exchange both matter and energy with the surroundings.
D. Cannot exchange either matter or energy with the surroundings.

Explanation

### Step-by-Step Solution

1. **Understanding System Types**: In thermodynamics, there are three main types of systems: open, closed, and isolated systems. Each type has different characteristics regarding the exchange of energy and matter with the surroundings.

2. **Open System**: An open system allows both energy (in the form of heat) and matter to be exchanged with the surroundings. For example, a beaker of water that is heated without a lid is an open system, as both heat and water vapor can escape into the environment.

3. **Closed System**: A closed system, on the other hand, can exchange energy (heat) but not matter with its surroundings. For instance, a sealed container of water that is heated can transfer heat to the surroundings, but the water inside cannot escape.
