One difference between a violation and an invasion is:
a. invasions tend to be less intentional than a violation
b. violations are more likely to be short-term than invasions
c. violations are more active and purposeful than invasions
d. violations are longer lasting than invasions

B). Violations are more likely to be short term than invasions.

Explanation:

Violation exemplifies the act of being violated(ignored) or transgression of a law, promise or rule which is short-termed and usually unintentional while on the contrary invasion is a deliberate and intentional attempt to intrude into an area where they are not wanted usually by military men in order to conquer a certain geopolitical entity. Thus, in comparison invasions are more active, intentional, and long-lasting than the violations which are comparatively less active, unintentional and short-termed. Thus, this makes us conclude option B as the answer to the given question.
