The Correct Option is B

Step 1: Recall Gram classification.
- Gram-positive bacteria have thick peptidoglycan walls.
- Gram-negative bacteria have thin walls and outer membranes.
Step 2: Analyze each option.
- (A) {Campylobacter jejuni} → Gram-negative.
- (B) {Clostridium botulinum} → Gram-positive, anaerobic, spore-forming, causes botulism.
- (C) {Vibrio cholerae} → Gram-negative, causes cholera.
- (D) {Salmonella typhi} → Gram-negative, causes typhoid fever.
Step 3: Select correct Gram +ve.
Only {Clostridium botulinum} fits. Final Answer: \[ \boxed{\text{Clostridium botulinum (B)}} \]
