b. broadswords and spears

c. bow and arrows

d. short daggers

e. lengthy bows and arching swords

The correct answers is e. lengthy bows and arching swords.

Explanation:

Even though Night Attack on the Sanjo Palace comes from the 13th Century, the events painted there had happened the century before. It comes in a very traditional Asian format called emaki, which is a big roll that contains the work; this roll was intended to look at every section in detail. Long bows and arching swords are used by Japanese samurai in all the painting, that is why e is correct.
