Correct Answer: PRSQ

Solution : The correct option is the second option.
Explanation:

• P. A man in a maroon colour flannel shirt
• R. which had been purchased for purposes of decoration
• S. and made principally by some Jewish women on the East side of New York
• Q. rounded a corner and walked into the middle of the main street of Yellow Sky

The sentence begins by introducing a man wearing a specific maroon-coloured flannel shirt. This description sets the stage for the central figure in the scene. Following that, there's a relative clause providing additional information about the shirt, explaining its origin or significance. Then, another clause is added to further elaborate on the shirt's creation , attributing its making to a group of specific individuals in a particular location. Finally, the sentence concludes by describing an action taken by this man in the described attire

Therefore, the complete sentence should be, "A man in a maroon colour flannel shirt, which had been purchased for purposes of decoration and made principally by some Jewish women on the east side of New York, rounded a corner and walked into the middle of the main street of Yellow Sky."
