Final answer:
The false statement about the Undead is that they have more strength between sunrise and sunset, as vampires are traditionally stronger at night.
Step-by-step explanation:
The statement about the Undead that is NOT true is: 'they have more strength between sunrise and sunset'. In many myths and stories, including Bram Stoker's novel about Count Dracula, vampires are known to possess heightened powers or strength during nighttime and are usually weaker during the day. Their characteristics typically include intolerance to holy objects and garlic, the ability to transform into other animals or matter, and a limitation in not being able to cross moving water unless carried.
