The period known as Japan's "golden age of culture was most closely associated with

B. Zen Buddhism.
c. the rise of the merchant class.
D. the code of bushido.

A: The Heian Court

Explanation:

Zen was not introduced as a separate school in Japan until the 12th century during the Kamakura period, when Nonin established the first Zen school known as the Daruma-school.

The rise of the merchant class broke apart japan, and it was definitely not their golden age.
