Answer:
a giant corporation composed of many smaller corporations.
Explanation:
This option is not 100% right, but the other options were completely wrong. A conglomerate is a corporation that operates in totally different and unrelated industries. For example, a conglomerate can operate in the energy sector, financial services, education services, cruise lines, and agriculture. No two industries are even related to one another, and that is what operates a conglomerate from a normal corporation. E.g. Samsung is a conglomerate because it operates an electronics business, manufactures cars, builds ships, operates funeral homes, etc.
