01. When Kalakanya attacked the body of Puranjana, the soldiers of the Yavana king entered the different gates of the city and began to trouble the citizens. This in essence means that
a) Puranjana was not careful enough to not allow Kalakanya to attack him
b) The gates of the city were not properly closed and hence was attacked
c) The citizens of the city were not devotees
d) When old age attacks, all the gates of the body are blocked by so many diseases and one becomes really miserable
