The optimization team is planning their next 3-month experimentation roadmap for the homepage. They have the following candidates:

A - 8 weeks to build, another estimated A weeks to complete (run), and a projected 20% lift in conversion rate. B - 5 weeks to build, another estimated 7 weeks to complete (run), and a projected 25% lift in conversion rate. C - 5 weeks to build another estimated 3 weeks to complete (run), and a projected 15% lift in conversion rate. D - Requires no development team resource, an estimated 7 weeks to complete (run), and a projected 10% lift in conversion rate.
