Final answer:
The correctly punctuated sentence is option a) 'Although I was late to work, I still got all my work done.' It correctly uses a comma to separate the dependent clause from the independent clause, ensuring clarity and readability.
Step-by-step explanation:
The correct punctuation of a sentence can greatly affect its clarity and meaning. We need to determine which of the given sentences is punctuated correctly. To do so, we should look at the guidelines for comma usage in conjunction with subordinating conjunctions and independent clauses.
Let's consider each option:
- Option a) Although I was late to work, I still got all my work done.
- Option b) Although I was late to work I still got all my work done.
- Option c) Although I was late to work I still got all my work done.
Option a) sets the dependent clause 'Although I was late to work' apart from the independent clause 'I still got all my work done' with a comma, which follows the rules of correct punctuation. This separation helps improve the readability and understanding of the sentence. Therefore, the correctly punctuated sentence is option a).
