Question

hammurabis code is important because it was the first code of laws to be
obeyed.
written.
published in books.
used in every ancient civilization.

Explanation:

Hammurabi's Code is historically significant as it was the first known written code of laws. The option "obeyed" is incorrect as laws were obeyed before, "published in books" is not accurate as the concept of book - like publication wasn't the same then, and "used in every ancient civilization" is false as it was specific to Babylon. The correct reason for its importance is that it was the first code of laws to be written.

Answer:

B. written
