To answer this question, we need to identify the invention from the provided choices that enabled cities to expand in size, specifically one that was invented in 1888. Here's a breakdown of the relevant options:

1. Electric Light: While significant, it was not invented in 1888 and primarily improved urban nightlife rather than city size.

2. Telegraph: Developed earlier in the 19th century, it improved communication but did not directly contribute to urban expansion.

3. Electric Streetcar: The electric streetcar indeed became popular in the late 19th century, facilitating easier public transportation and thus city expansion.

4. Automobile: While the automobile became significant in the 20th century, it did not emerge until after 1888.

5. Subway: The first subway systems began development later, notably in the early 20th century.

Conclusion

The correct answer is electric streetcar, as its invention and subsequent adoption allowed people to travel greater distances within urban areas, leading to city growth and expansion starting in the late 19th century.
