Final answer:
Mumps is the viral infection from the choices given that can lead to post-viral epididymitis, which is inflammation of the epididymis usually caused by a bacterial infection but can also be caused by viral infections.
Step-by-step explanation:
The associated viral infections that may cause post-viral epididymitis include primarily mumps. The mumps virus can lead to complications that affect the reproductive system of males, such as epididymitis and orchitis. Epididymitis can be either acute or chronic, with acute epididymitis typically having a rapid onset and most often caused by a bacterial infection. In contrast, viral causes such as mumps are less common but significant. In the context of this question, Tuberculosis (TB) is not a viral infection but a bacterial one, caused by Mycobacterium tuberculosis. Therefore, the correct viral infection from the options listed that could lead to post-viral epididymitis is b) Mumps.
