Answer:
D) They bound logs together and built a raft.
Enkidu steered it down the great river.
Gilgamesh carried Humbaba's head.
Explanation:
The question asked for the lines that proves that Gilgamesh is triumphant in battle. So, the lines
"They bound logs together and built a raft.
Enkidu steered it down the great river.
Gilgamesh carried Humbaba's head."
is definite proof of the victory of Gilgamesh for it mentions that the head of Humbaba is taken and carried by him. This means they have destroyed and killed him, definite proof of a victorious result. Only the fourth option shows the outcome of the fight while the rest three options just provide pieces of the action during the real fight.
