Elective abdominal ultrasonography of a 64 year old woman with past colicky pain but no current pain. It shows a mildly dilated common bile duct with what appears to be a gallstone (black arrow). The green and blue dots are blood flow, since the exam is done as a Doppler ultrasound to distinguish the bile duct from blood vessels.

A 64-year-old woman presents for an elective abdominal ultrasound. Several months ago, she experienced a few episodes of intermittent, moderate-to-severe right upper quadrant pain that resolved spontaneously within a few hours each time. She denies any associated fever, chills, nausea, vomiting, or jaundice during those episodes or currently. She has no significant past medical history other than well-controlled hypertension. On examination today, she is afebrile, her vital signs are stable, and her abdomen is soft and non-tender. Routine blood tests performed prior to the ultrasound, including full blood count, liver function tests (bilirubin, alkaline phosphatase, AST, ALT, GGT), amylase, and lipase, are all within their respective normal reference ranges. The provided image is a representative view obtained during her ultrasound examination. Considering the patient's history, current clinical status, and the findings demonstrated in the image, what is the most appropriate next step in the management of this patient?

A. Reassurance and discharge with advice to return if symptoms recur.
B. Magnetic resonance cholangiopancreatography (MRCP) for further evaluation.
C. Elective cholecystectomy alone.
D. Referral for elective endoscopic retrograde cholangiopancreatography (ERCP) or surgical consultation for stone extraction.
E. Urgent admission for intravenous antibiotics and pain relief.
