The correct answer is e. Produced only by Gram-positive species.
Bacterial exotoxins can be produced by both Gram-positive and Gram-negative bacteria. While it is true that many Gram-positive bacteria, such as Clostridium and Staphylococcus, produce exotoxins, some Gram-negative bacteria, like Pseudomonas and Escherichia, also produce exotoxins.
