Final answer:
The proportion of people who experience at least 1 ACE is 2 in 3, denoting that two-thirds of the population will undergo at least one adverse childhood experience. So, the option C. 2 in 3 is correct.
Step-by-step explanation:
The acronym ACE denotes Adverse Childhood Experiences, encompassing traumatic events transpiring before the age of 18.
To determine the prevalence, one must compute the ratio by dividing the count of individuals encountering at least one ACE by the total population.
Within the provided options, the accurate representation is "2 in 3," denoting that two-thirds of the population will undergo at least one adverse childhood experience.
This statistical insight underscores the significant impact of such events on a substantial portion of individuals, emphasizing the prevalence and importance of understanding adverse childhood experiences.
By expressing this ratio, the information becomes accessible and communicates a clear understanding that a significant majority—specifically, two out of every three people—will grapple with at least one adverse childhood experience during their formative years.
Therefore, the option C. 2 in 3 is correct for proportion experiences at least 1 ACE.
