Solution

The correct option is A Negatively charged
DNA is made up of a deoxyribose sugar, phosphate group, and nitrogenous bases. Phosphorus groups are negatively charged which imparts negative charge to the DNA. The charge of DNA and DNA fragments is the same.
Thus, option C is the correct answer.
