The time when the apartment building in downtown Milwaukee started on fire has been determined by the fire department, but what is more problematic to establish are the source of the flame, the mechanism by which it ignited the building, and the extent of the damage.
a. has been determined by the fire department, but what is more problematic to establish are
b. has been determined by the fire department, but what is more problematic to establish is
c. have been determined by the fire department, but what is more problematic to establish is
d. have been determined by the fire department, but what is more problematic to establish are
e. are determined by the fire department, but that which is more problematic to establish is
I choose the answer as A because we for verb in end we have "the source of the flame,<modifier>, and the extent of the damage", which i thought should be plural. Am I right, if I am wrong why?
