b. false

a. True

Explanation:

Congenital syphilis is the condition in which a baby is born with syphilis because his or her mother had syphilis during pregnancy. It can result in stillbirth, premature birth or miscarriage. If the baby is born successfully then they can have various birth deformities like lower extremity abnormality and saddle nose.

Saddle nose is the condition in which the nose bridge collapses so the height of the nose is drastically reduced. The depressed part may contain bone, cartilage or both. It can be corrected by plastic surgery. Apart from congenital syphilis saddle nose can also be caused by leprosy, cocaine abuse or nasal trauma.
