A 5-year-old female presents with a sore throat, low-grade fever, malaise, and a grayish exudate on the tonsils, pharynx, and larynx. This exudate is so extensive it has started to obstruct the child's breathing. Cultures of throat swabs indicated growth but no hemolysis on blood agar. Black colony growth was demonstrated on cystine-tellurite agar. PCR confirmed the presence of a toxin. Which one of the following represents the mechanism of action of this toxin? Select one: a. Blocks the release of stimulatory neurotransmitter acetylcholine at the presynaptic terminal b. Destroys cell membranes of red blood cells, leukocytes, and myocytes c. Functions as an adenylate cyclase d. Inactivates elongation factor-2 (EF-2)
