Answer:
It is True that product owners must create clear and unamiguous acceptance criteria for each product backlog item.
Step-by-step explanation:
Product owners play a very important role in software development effort. They develop the blueprint of a product like the features, when to build the product. So, clearly explaining the product backlog item is very important.
If the acceptance criteria is not clear it leads to confusion and the work is not done in a proper way and on the other hand if criteria are too rigid there will be no room for innovative solutions from the scrum team.The main aim of product owner is to find the right balance from both the ends.
