Final answer:
Children under 12 years of age must wear a life jacket on a 65-foot boat in Rhode Island.
Step-by-step explanation:
According to Rhode Island law, children under 12 years of age are required to wear a life jacket on a 65-foot boat. This means option A) Only children under 12 years of age is the correct answer.
Although all boats must have a US Coast Guard-approved wearable life jacket for each person on board, only those children under 12 years of age are mandated to wear them at all times while on the deck of any vessel that is under way. Adults and older children must have life jackets available but are not required to wear them at all times unless the boat is under 16 feet in length or if it is a canoe or kayak.
