The Idea-Expression Dichotomy is a foundational concept in copyright law. Which of the following correctly states its meaning?

The Idea-Expression Dichotomy is one of the most fundamental principles of copyright law it holds that copyright subsists in the form and manner in which an idea is expressed, not in the idea itself. In practical terms, this means that if two authors independently write novels about star-crossed lovers, neither can prevent the other from using the same basic idea only the specific creative expression is protected. This principle was first articulated by the US Supreme Court in Baker v. Selden (1879) and is now enshrined in Article 9(2) of the TRIPS Agreement, which expressly states that "copyright protection shall extend to expressions and not to ideas, procedures, methods of operation or mathematical concepts". In India, this principle is implicitly recognised through the requirement of originality under the Copyright Act, 1957 courts have held that copyright protects the skill and labour invested in expression, not the idea. This doctrine serves a critical social purpose: it prevents any single creator from monopolising ideas, thereby preserving the freedom of thought and expression for future creators.
