The Correct Answer is C
A cerebral concussion is a mild traumatic brain injury that occurs when a blow to the head causes the brain to move rapidly inside the skull, resulting in temporary changes in brain function. A concussion can cause confusion, memory loss, impaired concentration, dizziness, headache, nausea, blurred vision, and mood changes. Most concussions resolve within a few days or weeks with rest and monitoring.

Marfan syndrome is a genetic disorder that affects the connective tissue, causing problems with the heart, blood vessels, eyes, bones, and joints. It is caused by a mutation in the FBN1 gene, which encodes for a protein called fibrillin-1. Marfan syndrome follows an autosomal dominant pattern of inheritance, which means that only one copy of the mutated gene is needed to cause the disorder. A person with Marfan syndrome has a 50% chance of passing on the mutated gene to each child, regardless of the gender of the parent or the child.
