Based on your description, it sounds like the plan you are looking at might be Bramante’s plan. Bramante's design for St. Peter's Basilica included a Greek cross layout initially, which is often depicted in plans that highlight the central dome and equal arms.

However, if the plan you are seeing is notably long and rectangular, it could also refer to Maderno's plan, which extended the building into a longitudinal basilica form. Since you mention that the top room has a separate rectangular entrance, it could align with Maderno's modifications to accommodate the west entrance.

Without the actual image, it's difficult to make a definitive identification, but based on the information given, I'd lean towards **d. Maderno’s plan** if it emphasizes the elongated rectangular shape, as that is characteristic of his design.
