  2. spontaneous mutation by depurination

  3. induced mutation

  4. errors introduced during DNA repair

B Correct answer
Explanation

Loss of a purine base (A or G) to form an apurinic site (AP site) is depurination, which results into spontaneous mutation. AP site has neither a purine nor a pyrimidine base, either spontaneously or due to DNA damage.
