The CORRECT ANSWER IS A.
A. the dome
Step-by-step explanation:
Most churches are built and projected to be similar to a huge cross and at the points of intersection of the lines of the cross, a dome can be seen in most cases to be positioned above it, a lot of catholic churches of history are designed and constructed in that manner, having two altars stationed at the verges of the cross allocated to different saints and the major altar stationed at the top margin of the cross, with a huge dome in the middle.
The central dome, do acts as the prime focus of the church and stands for the way to heaven. These churches are mostly designed on a floor plan similar to a cross, to have four arms of equivalent length converge beneath the dome.
