What constitutes a "pilgrimage type" church?

A) It has additional perimeter buildings to house pilgrims.
B) It has its ambulatory directly attached to the nave.
C) It has radiating chapels along the transept and ambulatory.
D) It has a narrowed main aisle to create a dignified procession.

Pilgrimage type churches are characterized by their architectural features that accommodate large numbers of pilgrims. One of the key features is the presence of radiating chapels along the transept and ambulatory, which allowed pilgrims to visit various chapels dedicated to different saints without disrupting the main liturgical functions in the nave and choir. This design facilitated the flow of pilgrims, allowing them to pray at the relics housed in these chapels.
