Answer: A: Congenital stricture of urethra 
Explanation: Congenital Urethral Stricture-this rare condition may be associated with duplication of the urethra. Usually, symptoms are delayed until adolescence, when it may be indistinguishable from a stricture due to unrecognised urethral injury in childhood. A single treatment by optical urethrotomy(Direct visual internal urethrotomy) or dilatation is usually effective.Reference : page1362 Bailey and Love's sho practice of surgery 25th edition
