Final answer:
The conduct category in fitness standards that does not allow for a petition for consideration is 'conduct deemed a presumptive bar.' It is viewed as permanently and categorically disqualifying, with reconsideration only in exceptional circumstances.
Step-by-step explanation:
The category of conduct defined in the fitness standards for which a petition for consideration is not permitted is c) conduct deemed a presumptive bar. A presumptive bar typically involves activities or conduct that indicate a clear and significant risk to the trust required for a certain position, often related to national security or law enforcement.
This means that applicants who engage in activities that fall under a presumptive bar are generally considered ineligible, with only exceptional circumstances allowing for reconsideration. Unlike unacceptable or adverse conduct, which may be subject to review and possible waiver, or a temporary bar, which might allow for reconsideration after a certain time, a presumptive bar is more definitive in signaling that the behavior exhibited is categorically disqualifying.
