What is the waiting period before Robert will begin receiving Social Security disability benefits after qualifying?

The correct answer is five months because, under Social Security regulations, there is a mandatory waiting period before an individual can start receiving disability benefits. This waiting period begins after the date of the disability onset and lasts for five consecutive months. Benefits are not paid for the first five months of disability, even if the individual qualifies during that time. After this waiting period, Robert will begin receiving his Social Security disability benefits.

The other options, such as three months, six months, or one year, do not align with the established regulations regarding the waiting period for disability benefits. The three-month period is too short, while six months and one year exceed the standard waiting period, which is specifically set at five months.
