Answer:
b. Giotto's experience with living through the Black Death
Explanation:
Plague, also known as the Black Death, wasn't in full epidemic in Italy during Giotto's time, but it was certainly present in the areas around Florence and Sienna where he was living and working.
Giotto's work was influenced by Black Death, and his paintings became more dramatic and realistic as his surroundings and experiences were grimmer and filled with death than usual.
That is how Lamentation, a fresco depicting the death of Jesus Christ looked over by the angels and followers, is influenced by the plague. He used the real-life imagery of death and suffering over the illness that was present during his time, and used it to wake the emotional feeling that was caused by the death of Jesus Christ.
