The answer is E, D, B. The primary sore occurs after an incubation period of 3-4 weeks during which period Treponema pallidum is spreading in the blood.

The secondary lesions occur 2-3 months after infection and are characterized by skin rashes, alopecia and general malaise.

The typical lesions of the tertiary phase occur many years after infection and cause necrosis of internal organs, liver, testis and bones. The gumma is a necrotic granuloma.
