A 68-year-old male with known Hepatitis B related cirrhosis and a history of alcohol excess presents for routine surveillance. His alpha-fetoprotein (AFP) level, which has been stable at 15 ng/mL for the past two years, is now noted to be 185 ng/mL. A screening ultrasound performed three months prior was reported as showing diffuse parenchymal changes consistent with cirrhosis but no focal lesions. Due to the elevated AFP, a repeat ultrasound was performed, which identified a 2.5 cm nodule in segment VIII. To further characterise this lesion, a contrast-enhanced ultrasound (CEUS) was performed, and the images provided are representative findings from this study. The patient has well-compensated cirrhosis (Child-Pugh A) and no significant comorbidities. His liver function tests are within normal limits except for a slightly elevated GGT. Given the clinical context and the findings demonstrated in the provided images, what is the most appropriate next step in the management of this patient?

A. Discuss the case in a multidisciplinary team meeting to determine suitability for curative therapy.
B. Perform a core needle biopsy of the lesion for histological confirmation.
C. Proceed directly to surgical resection of the lesion.
D. Repeat the contrast-enhanced ultrasound in 3 months.
E. Initiate systemic chemotherapy with Sorafenib.
