Correct Answer » C
Explanation

- Achalasia cardia is a motility disorder characterized by:
- Failure of relaxation of lower esophageal sphincter
- Loss of esophageal peristalsis
Typical features include:
- Dysphagia for both solids and liquids
- Regurgitation
- Dilated esophagus
- Bird-beak/rat-tail tapering on barium swallow
“Irregular filling defect” suggests:
