Final answer:
The cancel policy for Donna when opting out of Trading Power Protection depends on the trading platform's terms and conditions. Donna may face restrictions or penalties for cancellation without Trading Power Protection.
Step-by-step explanation:
When Donna is confirming a unit for next month and has chosen to opt out of Trading Power Protection, the cancel policy would mainly depend on the terms and conditions specified by the specific trading platform or service she is using.
However, without Trading Power Protection, Donna may be subject to certain restrictions or penalties if she cancels her unit reservation.
For example, she might lose the ability to trade her unit for a different time or location, or she may be charged a cancellation fee.
It is important for Donna to carefully review the cancel policy provided by the trading platform or service before confirming her unit.
