Answer:

The correct answer is - C. Chelex extraction.

Step-by-step explanation:

Chelex extraction is a DNA extraction method that involves a Chelex100 chelating resin that prevents DNA degradation by traping the degradative enzymes and from potential contaminants.

In absence of this Chelex resin, a styrene polymer resin that binds metal ions that might inhibit downstream analyses. This process involves a commercially used Chelex 100 which is a styrene-divinylbenzene copolymer that has paired iminodiacetate ions, which act as chelating groups in binds metal ions.
