What Seems to Be the Most Plausible Reason That More

What seems to be the most plausible reason that more is known about the history of male sexuality?

A) Research shows that sexual pleasure did not become important for women until shifts in societal views in the late 1800s.
B) Most historical information was intended to relate to both males and females but formal writing conventions used masculine-based language.
C) Historically, women's voices were often silenced, resulting in more information and accounts related to men's lives and experiences.
D) Women tend to prefer more privacy in their sexual lives; thus, less is known about them.
