Answer: The bus driver, who only works weekdays, always waits for me when I'm running late
Explanation:
Hi, to answer this question we have to know what a nonrestrictive clause is, and how we use commas in these cases.
A nonrestrictive clause adds extra information that isn’t required to understand the main point of the sentence. A nonrestrictive clause should be set off from the main clause with commas.
In this case, the main clause is:
The bus driver always waits for me when I'm running late
And the nonrestrictive clause is:
Who only works weekdays.
So, the correct form is:
The bus driver, who only works weekdays, always waits for me when I'm running late.
