When do child benefits typically end under workers' compensation?

Child benefits under workers' compensation typically end at specific life events: death of the injured worker, marriage of the child, or when the child reaches the age of 18. This rule is established to ensure that benefits are provided to children while they are generally considered dependents, which aligns with common legal standards that recognize adulthood and independence at 18 or upon marriage.

While the other options may seem plausible, they do not accurately reflect the actual guidelines regarding child benefits. For instance, the age of 16 does not align with typical statutory age requirements for dependence, and completing high school does not necessarily signify the end of dependency in a legal sense. Additionally, benefits extending to age 21 would usually depend on specific circumstances or state laws but are not a standard threshold in all cases, especially when marriage or reaching age 18 alters dependency status. Thus, option B correctly identifies the conditions under which child benefits under workers' compensation terminate.
