Answer: c. provides continuing income protection for employees who become disabled and are unable to work
Step-by-step explanation:
Disability insurance is very helpful to people who get injured on the job and so are unable to work. The insurance would provide them with an income for a time so that they do not become destitute.
There are different types of disability insurance with varying lengths and long-term disability insurance is one of them. This one provides income protection for a longer time period and is very useful when the injury in question is quite serious or permanently disables the affected person.
