Essentially this passage has two clauses and two subjects 1. The periodand 2 the reason. Both are singluar. Hence the period entails the singular - has– and the reason entails – is- . B is the only choice that befits this norm.
what i feel is the reason is not the subject of later part,
rather what is much more difficult to determine is the subject.
and after is/are is a list x,y,and z format
and list should be considered as one piece.
