Final answer:
The best alternative equipment for someone who has difficulty with floor exercises is a chair, as it allows for seated exercises and provides support for standing exercises. So, the correct answer is option 1.
Step-by-step explanation:
The alternative piece of equipment for participants who have difficulty getting up and down off the floor is a chair. A chair can be used for seated exercises or exercises that require standing but offer support.
Other items listed such as a yoga mat, resistance band, and jump rope typically require more mobility and may not be suitable alternatives for someone with difficulty moving to or from the floor.
