A 10-year-old boy is diagnosed with acute osteomyelitis of the distal femur. The metaphyseal location of hematogenous osteomyelitis in children is primarily attributed to which of the following anatomical features?

- B.Continuous capillary network crossing the physis into the epiphysis
- C.Thick cortical bone providing a rich nutrient supply
