Answer :

Answer:

a. Metropolis

Explanation:

a. It is a metropolis because a metropolis is a city that is busy and important.

b. It is not a megacity (this answer was made via process of elimination and megacity doesn't seem like it).
c. It is not a primate city as a primate is basically something like a monkey.

d. It is not a higher-order city since higher-order cities are more distributed and are fewer in numbers.
