Parallelism means that the same form of words is used in the entire group of words. So, here, I believe that the correct answer should be to take a warm shower, to dry myself off, to comb my wet hair.As you can see here in this group, all words start with an infinitive - to + verb, and have the same form, thus, this should be the option to choose.
<h2>the answer is <u>to take a warm shower </u><em>Parallelism means that the same form of words is used in the entire group of words</em> . . . . hope it helps</h2>
