Final answer:
The correct way to revise the sentence is by using a comma after 'However' and before 'Max,' without separating 'black cat' with commas: "However, nothing is better than watching movies with my loyal black cat, Max."
Step-by-step explanation:
The correct revision for the paragraph presented would be option C: "However, nothing is better than watching movies with my loyal black cat, Max." This version uses a comma after the transitional word 'However,' properly setting it apart from the rest of the sentence. Also, it doesn't comma-separate 'black cat' as that phrase is considered a compound modifier of 'Max' and should remain together without a comma. This creates a clear and grammatically correct sentence structure, which helps in conveying the message effectively. When adding descriptive words such as 'loyal' and 'black' before the noun (cat), the word 'loyal' is separated by a comma before the compound adjective 'black cat.' The name 'Max' is then appropriately set off with a comma to indicate it as an appositive, giving more information about 'my loyal black cat.'
