Final answer:
Andrew must have no fear of heights or confined spaces to become a Coast Guard boarding officer. Being a Coast Guard officer and meeting the minimum height requirement are also important qualifications.
Step-by-step explanation:
In order to become a Coast Guard boarding officer, Andrew must meet several qualifications. One of the special qualifications he must meet is having no fear of heights or confined spaces. This is important because boarding officers often have to navigate through tight spaces on ships or climb heights to carry out their duties.
While being a Coast Guard officer is not listed as a special qualification, it is a prerequisite for becoming a boarding officer. Therefore, option B is also correct. Additionally, Andrew must meet the minimum height requirement of 65 inches (option D) to ensure he can effectively perform his duties on board the vessels.
