Concept:Copyright legally protects the original expression or fixed form of a creative work, not the underlying idea itself.
Explanation:Under copyright law, protection applies only when an idea is given a concrete, material form such as a written text, a painting, a song, or a software code.
The law deliberately separates the underlying idea from its expression.
Anyone may freely use the same idea, provided they express it in their own distinct and original way.
For instance, many textbooks can explain the same programming concept, yet each textbook's particular wording and layout is separately protected by copyright.
Profit is simply a financial gain and does not qualify as copyrightable subject matter.
Inexperience is a personal trait and has no relation to creative works or intellectual property protection.
Hence, among the given options, copyright protects the expression of ideas rather than the ideas themselves.
