Here, "each" is a noun/pronoun (I'm not sure how you'd classify it) that is the subject of "blames".
E.g.,
I thought both statements were necessary to solve this DS problem, but each actually solves it individually.
each (subject) ... solves (verb)
By the way, your interpretation seems to be valid, although it is stylistically awkward. (Style is not tested on this exam.)
However, that choice is still incorrect because "the other person" doesn't work for this kind of meaning. Reciprocal relationships are described by just "the other" or "each other""”"”NOT "the other (noun)".
E.g., if we're talking about a divorcing husband and wife"”
Each blames the other for the breakdown of the marriage
"”> The husband blames the wife; the wife blames the husband.
Each blames the other person for the breakdown of the marriage
"”> Here, "the other person" is some third person"”"”presumably someone who has already been mentioned (or whose identity is obvious to the people talking). E.g., "the other person" could be someone with whom one of the spouses had an extramarital affair.
Note that, in this sentence, the husband and wife are actually agreeing about whom to blame.
