Answer: The statement that is true about dictionaries is:

“Every key must be unique.”

In a dictionary, each key is associated with a single value, and these key-value pairs are used to store and retrieve data. Dictionaries in programming languages like Python require that keys be unique. This uniqueness ensures that each key corresponds to a specific value and prevents ambiguity when looking up values based on keys. If you attempt to use the same key multiple times in a dictionary, the new value will simply overwrite the old value associated with that key.
