The correct answer is A. The sky was blue this morning; nevertheless, rain was expected.
Explanation:
The semicolon (;) is a punctuation mark that has different functions in terms of grammar these functions include separating items in a lists, especially if these are long or contain details; linking two independent clauses (sentences that are complete) directly; and joining two or more independent clauses through a conjunctive adverb such as <em>however, consequently, therefore </em>or<em> nevertheless</em>. Additionally, it is important to avoid replacing a comma or other punctuation mark with a semicolon or using semicolon to link two idependent clauses when these are already link by conjunctions such as <em>or, but, and</em>. Considering this, the choice or statement that shows the proper way to use a semicolon is "The sky was blue this morning; nevertheless, rain was expected" because in this statement the semicolon links two independent clauses (each with a subject and verb) "The sky was blue this morning" and "rain was expected" by using a conjunctive adverb which in this case is "nevertheless" and therefore the use of semicolon follows the grammatical rules and shows the correct way to use this punctuation mark.
