An economic system based on competition for market shareGroup of answer choicesGlobalizationTariffColonialismCapitalism

The economic system based on competition for market share is most accurately described as Capitalism.

Explanation:

1. Capitalism refers to an economic system where private individuals or businesses own capital goods, and production is based on supply and demand in a free market. It fundamentally promotes competition among businesses seeking to maximize their profits and market share.

2. Globalization is a broader concept that refers to the process of interaction and integration among people, companies, and governments worldwide, often driven by trade, investment, and technology. While it can influence competition, it is not an economic system in itself.

3. Tariff is a tax imposed on imported goods and is used as a policy tool rather than an economic system.

4. Colonialism involves the control of one nation over another and economic exploitation, which is different from a competitive market system.

Thus, the correct answer is Capitalism.
