No, your answer is not correct. The correct answer is d. "Edit of Japan" (also known as the "Sakoku Edict" or "Closed Country Edict").

To arrive at the correct answer, you can follow these steps:
1. Read the question carefully to understand what is being asked.
2. Focus on the key details given in the question, such as the year (1635) and the fact that the policy forbids anyone to leave or enter Japan.
3. Identify the options provided and determine which one matches the description of the policy issued in 1635.
4. Eliminate options that don't match the given details:
- The "Tang Shogunate" and the "Edit of Milan" are not relevant to Japan's history in the year 1635, so we can eliminate them.
- The "Edit of Nantes" was a religious freedom decree issued in France in 1598, which also doesn't match the description provided.
5. The remaining option is d. "Edit of Japan," which is the correct answer.

Therefore, the correct answer is the "Edit of Japan" (Sakoku Edict/Closed Country Edict).
