Good explanation on reddit: https://www.reddit.com/r/step1/comments/d8aqj5/spoiler_nbme_16_hey_can_anybody_advice_how_to_get/
Essentially, A = mucinous glands (foamy cytoplasm) B = parietal cells (stain eosinophilc, P ar I etal cells stain PInk w/ a fried egg appearance. Additionally, they're above chief cells C = chief cells (stain basophilic, super dark, and below parietal cells)
first should know that this is the fundus or body of the gastric, so it should be the parietal cell domaine; then think the mucus is the protective one , A without hesitate. then the other on the upper glandular layer should be the paretal cell, which is B. others like C is so small ,in the deeper glandular layer and basalphilic looking maybe is the chief cell . then deeper could be the submucosa layer.
