Concept:
Capitalism is an economic system characterized by the private ownership of the means of production, the focus on generating surplus value, and market-based distribution.
Step 1:
A defining feature of capitalism is the commodification of labor power, where workers sell their labor for wages, and the employer closely monitors the cost of production to ensure efficiency.
Step 2:
Capitalist economies are centered on the large-scale production of goods and services destined for exchange in a competitive market rather than for direct personal consumption.
Step 3:
The ultimate driving force of a capitalist economy is the pursuit of profit; capital is reinvested into the production process to generate further surplus value and capital accumulation.
Step 4:
"Feudal lords" (B) are central to the feudal system, a pre-capitalist structure, and "Barter exchange" (D) represents a pre-monetary economic model, neither of which defines a modern capitalist economy.
Step 5:
Because A, C, and E accurately reflect the mechanisms of a capitalist system, option (2) is the correct choice.
$$\boxed{\text{(2) A, C, E Only}}$$
