The probability for a harmful occurrence that is technically possible, but improbable, is Seldom.
The correct answer to the given question is option C.
The probability for a harmful occurrence that is technically possible, but improbable, is Seldom.
According to ATP 5-19 Table 1-1, the terms used to describe the probability of a harmful occurrence are categorized into five levels: __extremely likely__, __likely__, __unlikely__, __seldom__, and __never__.
In this case, a harmful occurrence that is technically possible but improbable would be classified as Seldom. This means that while there is a possibility of it happening, it is expected to happen very rarely or infrequently.
