Yes correct,
this is yersinia enterocolitica which causes pseudoappendicitis clinical picture and it produces heat stabel enterotoxin.

choice A: yersinia pestis is coagulase positive but not enterocolitica
choice C: rectal prolapse is caused by whipworm
choice D: TCBS is for vibrio
choice E: It's not sexually transmitted but fecal-oral transmission
