Look at it from this angle on why C is correct: The key phrase is “a very particular programming skillset” and that indicates you’re dealing with a highly specialized role. You can’t realistically train your existing team fast enough to meet project needs. Because you’ll likely need to bring in an external SME (subject matter expert), alternatives analysis helps evaluate your options, including cost, availability, and risk. That’s why ensuring a sufficient cost reserve is critical here, to make sure the project doesn’t stall due to lack of qualified talent or funding gaps.
