The Huangpu River, a major waterway in China, flows through the city of Shanghai, explaining why option 3 is the correct answer.

Now let`s evaluate the other three options:

Option 1 suggests Beijing, which is incorrect. Although Beijing is the capital city of China, the Huangpu River does not flow through it. Major rivers that flow through Beijing include the Yongding and Chaobai Rivers.

Option 2 suggests Ho Chi Minh City, which is also incorrect. Ho Chi Minh City is a major metropolitan city located in Vietnam, not China, therefore the Huangpu River does not flow through it.

Option 4 names Manila, which again is an incorrect response. Manila is the capital city of the Philippines, and so it has no geographic connection with the Huangpu River.

To sum up, Shanghai is the only city among the options provided through which the Huangpu River flows.
