The familial cancer syndrome that exhibits autosomal recessive inheritance among the options listed is "Fanconi's anemia."
It is a rare genetic disorder characterized by bone marrow failure and physical abnormalities.
It is inherited in an autosomal recessive pattern, which means an individual must inherit two copies of the mutated gene (one from each parent) to develop the disorder.
