The statement that is true here is:
The monarchs of the United Kingdom have limited power
Explanation:
The monarchs of the United kingdom can retain their position as the monarchs but they have no real rights in the government except for a few drastic ones.
Some powers they have include the power to dissolve the government which is not something that they have exercised for years.
Rest of the time, the Monarch in the UK is more symbolic and nominal to represent the tradition of the people of UK than anything else.
