Final answer:
The 1930 Production Code, or Hays Code, did explicitly forbid complete nudity in movies, making the answer to the student's question 'a) True'. This code also forbade homosexual content, reflecting the media censorship norms of that era.
Step-by-step explanation:
The 1930 Production Code, commonly referred to as the Hays Code, indeed explicitly forbade complete nudity along with a list of other guidelines that were meant to regulate the content of motion pictures. The aim of the code was to prohibit content that was considered morally questionable, which included nudity. Therefore, the answer to the student's question is a) True.
In the broader context of media censorship during the early 20th century, the Hays Code also forbid the portrayal of homosexual content in movies, following a precedent set by different bans like the one in New York state against theater productions promoting homosexual content. This was part of a broader pattern of avoiding the publication of positive portrayals of gay, lesbian, and transgender people in various forms of media, due to concerns over legal prosecution.
