all of them are correct.
the first two have exactly the same meaning; you'd use the first only when the extra words 'to be' are justified, either because they resolve some sort of ambiguity or because there's just A LOT of stuff between 'X' and 'Y'.
examples:
Most Americans consider Beverly Hills, a ritzy suburb to the north of Los Angeles, to be a desirable place to live. <-- possible ambiguity (could mean l.a. is desirable) if you don't include 'to be' here
Most Americans consider Beverly Hills a desirable place to live. <-- no ambiguity, so 'to be' would be unnecessarily wordy

'consider as' means 'consider in the capacity of or in the role of'. for instance:
Considered as a work of art, Grant Wood's "American Gothic" is wholly unremarkable; considered as a depiction of everyday 1930's Americana, however, it is a classic piece. <-- i.e., the piece is unremarkable [i]from the standpoint of art, but remarkable from the standpoint of american historical portrayal.

Explanation:The original sentence contains the unidiomatic "considered as being". The correct idiom is simply "considered", as in "I considered you a friend." Also, "was the subject...over the years" is incorrect. The sentence should use the present perfect "has been the subject," since the speculation began in the past and continues to the present. Finally, "attributed by" is not the correct idiom for this sentence. It should be "attributed to."
(A) This choice is incorrect as it repeats the original sentence.
(B) This choice repeats the original idiom error "considered as," though it corrects the other two errors.
(C) This choice repeats the original idiom error "considered to be" (with a slight variation) as well as the verb tense error "was."
(D) CORRECT. This choice corrects all of the original errors: "considered" instead of "considered as"; "has been" instead of "was"; and "attributed to" instead of "attributed by."
(E) This choice repeats the original idiom error "considered to be" (with a slight variation) as well as the verb tense error "was." It also introduces new errors: "or any other language" was removed from the sentence entirely, which changes the meaning; "over the years" is placed awkwardly; and "he had not been" is in the past perfect tense, when the correct tense is simple past.
Explanation to option B and C says :
-- idiom error "considered as,"
-- idiom error "considered to be"
