    Correct Answer: heating


    Solution : The correct option is heating.

    When DNA is heated or denatured, it becomes hyperchromic. The absorption of UV light rises as the DNA strands split, owing to the breakage of hydrogen bonds between complementary base pairs, resulting in hyperchromicity.
