E. The dancers must take time to completely warm up before the performance.

Explanation:

Sentences A and E contain split infinitives. In the case of sentence "A" the adverb "quickly" is between the particle "to" and the verb finish. Then, we can see that the same happens with sentence "E" in which there is an adverb (completely) between the particle "to" and the verb "warm up".

To have an splt infinitive is necessary to place something (usually an adverb) between the particle "to" and the verb. So sentences B, C, D are not examples of split infinitives.
