In journey to the center of the earth chapter 20-21
what danger do they not face by chiseling a hole in the wall to get to the water?
a. the wall may crash down and crush them.
b. the water might come out and drown them all.
c. they might not get to the water at all.
d. they could set off an interior earthquake of sorts.

The correct response is Option C: They might not get to the water at all.

Explanation:

There is no danger that the travelers in the novel will not find water when they happen upon the cliff because it is obvious this point is a source of water. The character Hans had set off in the story in search of water for the group. The water could be heard moving on the other side of the granite cliff. At this point in their journey, the travelers had begun to ration their water so Hans' discovery was a relief, although it implied some risks.  

i believe that's the correct answer
