Be cautious of picking a task that represents a large portion of the work associated with the position. Keep your answer concise and remain positive, focusing on what you do to make the difficult task more manageable for you.

"I find the Affordable Care Act (ACA) to be the most difficult part of Benefits. There are so many complexities when it comes to determining who is eligible and calculating hours and completing the annual forms for the IRS. I know I can become an expert though, just as I did with FMLAs, so I'm working my way through a series of courses offered through my current employer's ACA vendor to learn more about it. I also offered to assist my manager with reviewing employees' ACA hours since I know the more I work with it, the easier it will become for me."
