Primary sex characteristics refer to which of the following?

Explanation:
Primary sex characteristics are the parts of the body that are directly involved in reproduction, such as the gonads and the reproductive organs. The key idea is their direct role in making reproduction possible, not simply how they look on the outside. Many of these structures develop or change inside the body and aren’t visible externally, which is why describing them as non-visible fits well. In puberty, these are the changes that relate to the organs needed for producing offspring, rather than features that signal maturity to the outside world. By contrast, the visible, outward changes that don’t directly participate in reproduction are what we call secondary sex characteristics. So the best match is changes involved with reproduction that are non-visible, since primary sex characteristics focus on the reproductive system itself, many of which are internal.
