Yes, B is the right answer. And you're very welcome.

To determine which of the sentences is punctuated correctly, we need to look at the use of commas and conjunctions in each sentence.

1. The cord winds around the pole, and across the door frame.
This sentence is punctuated correctly. The comma is used before the coordinating conjunction "and" to separate two independent clauses: "The cord winds around the pole" and "across the door frame."

2. The wind blew fiercely, and the door slammed shut.
This sentence is punctuated correctly. The comma is used before the coordinating conjunction "and" to separate two independent clauses: "The wind blew fiercely" and "the door slammed shut."

3. The boy slept, and wouldn’t budge when his mom tried to wake him.
This sentence is punctuated incorrectly. The comma is used incorrectly before the coordinating conjunction "and." Instead, a semicolon (;) should be used to separate two independent clauses. The correct punctuation would be: "The boy slept; and wouldn’t budge when his mom tried to wake him."

Therefore, the correct sentence with proper punctuation is: "The cord winds around the pole, and across the door frame."
