Correct: B — free fluid in the abdomen on FAST is a reason to perform laparotomy. In blunt trauma the FAST examination is used to decide disposition in the *unstable* patient: free fluid in an unstable patient means intra-abdominal haemorrhage and mandates immediate laparotomy without further imaging — which is also why option A is wrong, since an unstable patient with peritonitis goes to theatre rather than the scanner. CT has the reverse sensitivity profile from that stated in option C: it is excellent for solid organ injury and relatively insensitive for hollow viscus and mesenteric injury. Diagnostic peritoneal lavage is highly *sensitive* but poorly specific, which is the reason it has been largely abandoned (option D).
