Which of the following is true about copyright?

The assertion that copyright lasts for the lifetime of the creator plus 70 years is accurate. This duration is established under many copyright laws, including those in the UK and the US. It means that the creator has exclusive rights to their work during their lifetime, allowing them to control its distribution, reproduction, and public performance. After the creator's death, those rights are maintained for an additional 70 years, benefiting the creator's heirs or estate, which incentivizes the creation of new works and provides financial advantages to the creator's family.

The other statements do not accurately represent copyright laws. Copyright does not protect ideas alone; it protects the expression of ideas in a tangible form, which is crucial for upholding creative integrity. Copyright also extends to both physical and digital products, covering a wide array of creative works, and it cannot be renewed indefinitely, as the rights eventually expire after a set period, allowing the work to enter the public domain.
