Final answer:
The correctly punctuated sentence is "She traveled to London, England, in June 2022." Commas are used to separate the city from the country and to set off the year when following a date.
Step-by-step explanation:
The question relates to identifying the properly punctuated sentence. Punctuation is crucial for clarity and meaning in written communication.
When listing a city and country or a city and state, it is standard to use a comma after the name of the city and another comma after the state or country if the sentence continues.
Therefore, the correctly punctuated sentence is "She traveled to London, England, in June 2022." The commas correctly separate the elements of the geographical reference and the time reference.
