The correct answer is option 1: Copyright.
Copyright is a type of intellectual property right that protects original works of authorship, such as literary, artistic, musical, and dramatic works. It is automatically granted to the creator of the work as soon as it is created and fixed in a tangible form, such as writing it down or recording it. Registration is not required to obtain copyright protection, although it is recommended as it provides additional legal benefits.
Option 2: Patent refers to the exclusive ownership rights granted to inventors for their inventions. However, patents require a formal registration process, including a detailed application and examination by the patent office, to be granted protection.
Option 3: Industrial design provides protection for the visual aspects of a product, such as its shape, pattern, or color. Like patents, industrial designs also require registration to be protected.
Option 4: Trademark offers protection for distinguishing marks, such as logos, names, and slogans, that identify and distinguish goods or services from those of others. Trademark registration is necessary to obtain legal protection for the mark.
