A Correct answer
Explanation

A chancre is a painless ulceration (sore), most commonly formed during the primary stage of syphilis. This infectious lesion forms approximately 21 days after the initial exposure to Treponema pallidum , which is the gram negative spirochaete bacterium yielding syphilis. These ulcers usually form on or around the anus, mouth, penis and vagina.
