Final answer:
The sentence with a misplaced modifier is 'The band played songs for the crowd with guitars.' This suggests the crowd has guitars, which is incorrect. Proper placement of commas was also demonstrated for various sentences.
Step-by-step explanation:
The sentence that contains a misplaced modifier is:
b. The band played songs for the crowd with guitars.
The misplaced modifier 'with guitars' suggests that it is the crowd that has guitars rather than the band. The sentence should be rewritten for clarity, perhaps as 'The band, with guitars, played songs for the crowd' or 'The band played songs with guitars for the crowd.'

- Though Susan wasn't feeling well, she went to the store anyway and bought ice cream, pizza, and candy.
