The correct answer is: C. Agents
An agent is a software entity that can be viewed as an autonomous entity that is situated in an environment and that is capable of perceiving that environment and taking actions that affect it. Agents can be represented by a set of attributes, such as their name, their goals, their capabilities, and their environment. However, agents are not limited to being represented by a set of attributes. They can also be represented by a set of rules, a set of procedures, or a set of functions.
A program is a set of instructions that tells a computer what to do. Programs can be represented by a set of attributes, such as their name, their purpose, their input, their output, and their algorithm. However, programs are not limited to being represented by a set of attributes. They can also be represented by a set of data structures, a set of control structures, or a set of functions.
The three-dimensional configuration of
a protein molecule is the arrangement of the atoms in a protein molecule. The three-dimensional configuration of a protein molecule can be represented by a set of attributes, such as the name of the protein, the number of atoms in the protein, the type of each atom, and the position of each atom. However, the three-dimensional configuration of a protein molecule is not limited to being represented by a set of attributes. It can also be represented by a set of coordinates, a set of bonds, or a set of angles.
