A 29-year-old with a chlamydia infection will likely exhibit which of the following?

A chlamydia infection often presents without noticeable symptoms, particularly in men where it can be asymptomatic. This aligns with the choice indicating unremarkable symptoms, as many individuals may not exhibit any clinical signs or obvious discomfort despite being infected. It's important to note that while some men might experience symptoms like urethritis or a small amount of discharge, a significant portion of cases are identified during routine screenings or by specific testing due to the absence of symptoms.

This characteristic of chlamydia makes it crucial for sexually active individuals to engage in regular screenings, as they could be carriers of the infection without knowing it. The other options, such as green penile discharge, urticaria, or penile ulcers, are not typical manifestations of chlamydia infection and would suggest other conditions or infections instead.
