Final answer:
Special needs passengers are usually allowed to board and disembark first in airline travel, providing them with necessary assistance and accommodation. So, the correct option is b) First.
Step-by-step explanation:
Special needs passengers typically board and disembark first to ensure their safety and provide them with the necessary assistance. The correct answer is: b) First. This boarding and disembarking procedure is designed to offer individuals with special needs, such as those requiring assistance due to mobility issues or disabilities, the time and support needed to comfortably settle into or exit the transportation vehicle. Boarding first allows staff or caretakers to provide assistance without time constraints, ensuring a smoother and more accommodating experience for passengers with special needs. This practice is a part of inclusive and considerate transportation policies aimed at prioritizing the well-being and convenience of individuals requiring additional assistance.
