Which type of corporation is formed primarily for business or profit?

The correct answer identifies a civil corporation as one that is formed primarily for business or profit purposes. Civil corporations are established to engage in commercial activities and generate profits for their shareholders. They focus on economic gain and are the most common type of corporation in the context of business enterprises.

In contrast, ecclesiastical corporations are organized for religious purposes, while eleemosynary corporations are primarily focused on charitable objectives. Lay corporations, though similar to civil corporations, typically refer to non-religious secular entities but may not exclusively operate for profit. The focus on profit and commercial operation distinctly characterizes civil corporations, making that the correct answer.
