Which of these sentences exhibits proper capitalization?

ANext Saturday afternoon, we are traveling to the great city of London.
BNext Saturday Afternoon, we are traveling to the great city of London.
CNext Saturday Afternoon, we are traveling to the Great City of London.
DNext Saturday afternoon, we are traveling to the great City of London.

Verified Answer :

The answer is A. This sentence capitalizes the first letter of the first word in the sentence, which is correct. It also has Saturday capitalized, and as Saturday is considered a proper noun, this is also correct. London, being a city, is another proper noun, therefore, it is necessary to have it capitalized. Sentence B can be identified as incorrect solely because 'afternoon' is capitalized. Afternoon is a noun, but not proper. Choice C makes the same mistake, as well as others. Finally, D capitalizes 'city,' which is not a proper noun. A proper noun is defined as a name that is used for a person, place, or organization.
