Nonrestrictive clauses are additional, non-essential information in a sentence. They are set off with a pair of commas (or in some cases, parentheses or dashes) to show that they are nonessential. Let's examine each sentence: Sentence A: My boss—who was recently promoted again—is great at motivating her employees. This sentence uses an em-dash (—) instead of commas to set off the nonrestrictive clause, which is acceptable but less common. Sentence B: My boss, who was recently promoted again, is great at motivating her employees. This sentence uses commas to set off the nonrestrictive clause, which is the standard and most common way to punctuate nonrestrictive clauses. Sentence C: My boss who was recently promoted again—is great at motivating her employees. This sentence uses an em-dash (—) incorrectly to separate the nonrestrictive clause. The first em-dash should be replaced with a comma. Sentence D: My boss, who was recently promoted again, is great at motivating, her employees. This sentence uses commas correctly to set off the nonrestrictive clause, but it adds an extra comma after "motivating" that is not needed.

Based on the analysis above, the sentence with the correct punctuation is: My boss, who was recently promoted again, is great at motivating her employees.
