European colonial domination of indonesia by the dutch imposed:

a. the legal use of gamelan music for all governmental events.
b. a religious conversion to strict christianity throughout the area.
c. a unified cultural expression throughout a vast archipelago.
d. geographical borders and single rule over highly diverse peoples.

The answer is d.) Geographical borders and single rule over highly diverse peoples.

Explanation:

When the Dutch arrived in the Archipelago at the end of the 16th century, they did not immediately start colonizing the Indonesians. Colonization of Indonesia by the Dutch was a process that occurred gradually under single rule; firstly, by Herman Willem Daendels (Governor-General: 1808 to 1811), and successively by rulers, who, over the course of hundreds of years, used all available political means of expansion to create geographical borders and boundaries that were the foundation of modern-day Indonesia.
