We definitely need "that" at the end of the answer choice because we have a "so" phrase to start the sentence. So *X* that *Y*. Eliminate A and D.
B gives us another "so", but we don't need it right before "that". "So dogged...so that" does not work. We're down to C and E.
The biggest difference between them is that E gives us a "so" to start the second phrase and C does not. Do we need it? In this case, yes, to maintain parallel form. We have a "so *X* that *Y*" cause and effect relationship, but we have two causes for one effect. "So dogged..., so persistent..., that". The two opening phrases are playing the same role, so they should be parallel.
