I thought the best answer is B.

I think B is correct :)

I agree.

To determine the correct answer, let's analyze each option:

A. "Under the Tokugawa peace, daimyo were prohibited from coining money." To confirm if this statement is true, we need to examine historical resources. You can consult history textbooks, peer-reviewed articles, or reliable online sources about the Tokugawa period to verify if daimyo were indeed prohibited from coining money.

B. "Under the Tokugawa peace, daimyo were heavily engaged in foreign trade." Similarly, you would need to research historical resources to determine if this statement is accurate. Look for evidence that shows the extent of daimyo involvement in foreign trade during the Tokugawa period.

C. "Under the Tokugawa peace, daimyo's social status increased." To evaluate the validity of this statement, you should again consult historical resources. Find information about the social hierarchy and status of daimyo during the Tokugawa period to confirm if their social status increased under the Tokugawa peace.

D. "Under the Tokugawa peace, castle building was encouraged." Once more, you would need to rely on historical sources to determine if this statement is true. Look for information on the construction and importance of castles during the Tokugawa period and whether castle building was indeed encouraged.

By researching and analyzing these points, you can determine the most accurate answer to the question. Remember to rely on reliable historical resources to support your findings.
