 Answer the question below. Please respond with the option letter (A, B, or C) first. (HINT: Each PubMedQA instance is composed of (1) a question which is either an existing research article title or derived from one, (2) a context which is the corresponding abstract without its conclusion, (3) a long answer, which is the conclusion of the abstract and, presumably, answers the research question, and (4) a yes/no/maybe answer which summarizes the conclusion.) 

Question:
Vertical lines in distal esophageal mucosa (VLEM): a true endoscopic manifestation of esophagitis in children? 

Options:
{'A': 'yes', 'B': 'no', 'C': 'maybe'}'

I have the conclusion from the article indicating that VLEM shows moderate to severe inflammation and may be specific to esophagitis in children. The question asked is whether VLEM is a true manifestation of esophagitis — and the conclusion supports a "yes" answer, which corresponds to option 'A'. I’ll respond with "A" first, then add a brief explanation with a citation as instructed. It’s important to follow the guidelines carefully!
