Choose the sentence that can end the text (in Question 31) most appropriately.

Although "Bac Bling" is popular in some parts of Vietnam, it has made an insignificant impact on tourism.

To sum up, while the song is popular, it does not effectively promote the beauty of Vietnam.

Moreover, the song's lyrics make it a symbol of Vietnamese culture.

Therefore, "Bac Bling" is not just a song but also a reflection of Vietnam's cultural identity.
