id go with Mid esophageal, seeing that lower esophageal and gastric funds would cause more of a gastric bleed rather than an esophageal bleed. The rest can't be true.
Hope this helps.

Oops my bad.

Mid esophageal = esophageal plexus of veins,
Lower esophageal and fundus + greater curvature = left gastric vein,
Antral = pyloric vein drain into portal,

The majority of blood from the esophagus is drained via the esophageal veins, which carry deoxygenated blood from the esophagus to the azygos vein, which in turn drains directly into the superior vena cava. These veins have no part in the development of esophageal varices. The remaining blood from the esophagus is drained into the superficial veins lining the esophageal mucosa, which drain into the left gastric vein (coronary vein), which in turn drains directly into the portal vein. These superficial veins (normally only approximately 1mm in diameter) become distended up to 12 cm in diameter in association with portal hypertension.

Lower esophagus is the site of portosystemic anastomosis, so it shud be
lower esophagus.

lower esophagus is one of the sites of portosystemic anastomoses where
varices occur.

Left gastric vein anastomoses with portal vein.
