Osteogenesis imperfecta is a rare human condition caused by a mutation in a gene encoding Type I collagen. In some forms of the disease, the mutation leads to the production of procollagen that has a defective extension sequence; this defect interferes with the assembly of functional collagen fibers. Which of the following symptoms would you expect to see in individuals with osteogenesis imperfecta?

A. thin discs between vertebrae B. defective kidneys and capillaries C. very strong tendons and ligaments/tight joints D. very weak bones E. respiratory problems/lung defects
