Which sentence is correctly punctuated?

Question

Accepted Answer

The correct option is 4:
The fourth option, "Ms. Jones went to dinner with Mr. and Mrs. Brown.", is correctly punctuated according to standard English conventions. Proper nouns, such as names (Jones, Brown), must always be capitalized. Additionally, titles or honorifics like "Ms.," "Mr.," and "Mrs." are typically followed by a period when abbreviated in American English, and they must always be capitalized as they are essential parts of a person's title. Since the sentence is a declarative statement, it correctly ends with a period. All elements adhere to the rules of capitalization and abbreviation punctuation.

The incorrect option is 1: This option ("Ms. Jones went to dinner with mr and mrs brown.") is incorrect because the titles "mr" and "mrs" are not capitalized. In addition, the surnames of the people, "brown," should be capitalized as they are proper nouns.

The incorrect option is 2: This option ("Ms Jones went to dinner with Mr and Mrs. Brown.") is incorrect because the title "Ms" is missing the period after the abbreviation (it should be "Ms."). While "Mr" is sometimes acceptable without a period in British English, the overall inconsistency and the missing period after "Ms" make this option flawed for standard punctuation.

The incorrect option is 3: This option ("ms. jones went to dinner with Mr. and Mrs. brown.") is incorrect because the first word of the sentence, "ms.," is not capitalized, and the proper noun "jones" is also incorrectly written in lower case. Furthermore, the proper noun "brown" is incorrectly written in lower case.
