Final answer:
Recall is the correct term for having lines memorized and not needing the script, which indicates the ability to access memorized information without cues.
Step-by-step explanation:
The correct answer to describe having one's lines memorized and not needing to have the script in hand is recall. Recall is the ability to access information without cues, similar to performing on stage without a script. In contrast, remember is a more general term for keeping information in your memory, recite means to repeat from memory, and memorize is the process of committing something to memory. Mnemonic devices are useful tools to help with the memorization process. For instance, using a mnemonic such as 'Mr. VEM J. SUN' to remember the order of the planets can help in retaining and recalling complex information.
