Personally I don't think its either of those, but if I were to choose one it would be the third. Those who live in glass houses should not throw stones.
Hangzhou was the Capital City of Song China.
Song Dynasty was divided into two distinct period; Northern Song and Southern Song.
Northern Song was from 960 to 1127 and its capital city was Bianjing, now known as Kaifeng.
Southern Song was from 1127 to 1279 and its capital city was Lin'an, now known as Hangzhou.
The last Chinese dynasty did not end in any of these options. Puyi was forced to abdicate in 1912 but was restored to the throne for a 11 days in 1917. In 1916, Yuan Shikai seized power and proclaimed himself emperor in 1916.

I don’t see your list of choices. Peasants were the poorest people and serfs were the most poor. Serfs could not own land. They were tied to the land and worked the land for higher classes. If I saw the choices, I could be more precise.
Have a nice day.
