Which of the following causes of mutations is incorrectly matched with its mechanism of action?

a. Spontaneous mutations: mistakes arise as long strands of DNA are duplicating themselves.
b. Radiation-induced mutations: energy disrupts atomic structure and breaks apart chromosomes.
c .Chemical-induced mutations: chemicals react with atoms in DNA molecules and induce mutations.
d. Spontaneous mutations: enzymes cause errors due to their highly erroneous nature.
e. None of the above is incorrectly matched with its mechanism of action.
