This question is poorly worded and as written doesn't provide an answer that matches any of the answer choices.

"Repeated" means to occur more than once.

Repeated no more than once could be interpreted as occurring at most twice, but wouldn't be written that way, regardless.

The provided answer matches wording of "no color occurs more than once"

Flag of one color: 4 choices
Flag of two: 4!/2!= 12
Flag of three: 4!/3! * 6=24
Flag of four: 4!=24

Total 64
