The correct options are B and C:

The writing system spread to other parts of Southeast Asia and influenced the development of scripts in neighboring countries.

C. Used irrigation canals and reservoirs to support large-scale rice farming: The Khmer civilization developed sophisticated irrigation systems, including canals and reservoirs, to support large-scale rice farming. This allowed them to sustain a high population density and develop a prosperous agricultural economy.

The other options are incorrect:

A. The Khmer civilization did not innovate a feudal system based on the loyalty of samurai warriors. This statement is more relevant to ancient Japan.

D. The Khmer civilization did not introduce Islam via Indian Ocean trade routes. Islam was introduced to Southeast Asia by Arab and Indian traders, and it spread through the region through a long process of cultural interaction, conversion, and adoption.

E. The Khmer civilization did build vast Buddhist temple complexes, most notably the famous Angkor Wat. However, although this influenced the religious and architectural landscape of Southeast Asia, it did not shape culture in the same way as the development of writing systems and the use of irrigation for rice farming.

To determine how the Khmer civilization shaped culture in Southeast Asia, we need to analyze each option and select the ones that apply.
