Which creature is used symbolically in most world religions?
a.) snake
b.)lion
c.)dove
d.)serpent

I would say Dove, because it mostly represents, like holy ghost, and like the God's Spirit.
Even look when Jesus got baptized, when he comes out of the water, the holy spirit, like a dove came down from heaven on him.
Hope that this helps you! =)

Dove - It symobolises peace therefore lots of world religions use it
