<span>A. The repetition of the phrase "when I watch you"</span>
I hope this helps. :)
If Walden Pond was unfathomed, then it was deep.
Unfathomed, in the context with water, can mean
that its depth is not certain, that the water is extending downward from the
surface. Unfathomed means it cannot be measured because it is extremely deep.
