Vincent, age 32, has recently experienced a panic attack for the first time in his life. He is worried that he will now develop a full-blown case of panic disorder. He should know that percent of adults have had a panic attack, but most do not go on to develop panic disorder.

23 %

Explanation:

From the question, we know that the person --vincent had panic attack. So let me explain what panic attack is.

When you start to feel something like pain in your chest, pain in your abdominal region, when you are short of breath, tingling occurs ,your body start to shake, your heart rate is much more faster and things like that do occur in a situation where someone is threatening you or maybe you lose your job and so on, that kind of emotional condition is known as PANIC ATTACK.

Because someone has panic attack does not mean that the person will have to have a panic disorder. According to reasearches, about 23 percent adults already encountered panic attack and most of them did not develop panic disorder.

so we know the answer cannot be c because no insect or animal starts as an adult

the answer is a. a swimming larvae

because since they are sea animals they automatticaly have to know how to swim they cannot just sink to the bottom

sorry if this is the incorrect answer.
