What is one of the exceptions under the Copyright Act 1968?

The correct choice highlights the concept of creative copyright, which refers to the rights creators have over their original works. The Copyright Act 1968 provides protection to authors and creators, granting them exclusive rights to use and distribute their creations. This includes literary, artistic, musical, and dramatic works. Creative copyright serves to incentivize innovation and creativity by ensuring that creators can control the use of their works and receive recognition and compensation for them.

The other options do not accurately reflect exceptions under the Copyright Act. Sharing all data publicly does not align with copyright principles, as it typically involves restrictions on the distribution of creative works. Mandatory licensing for all artists isn't stipulated in the Act, as licensing depends on individual agreements. Lastly, exclusion from teaching materials does not represent a recognized exception; rather, certain educational uses might still fall under fair use provisions despite copyright protections. Understanding these principles is fundamental for navigating copyright law and its applications in various contexts.
