INCORRECT This one has some meaning issue. 'Like the present, the past is constantly revised'.. Are we really revising the present ? Is that the intended meaning. Do not think so. The meaning must be in line of the fact that - as the present constantly changing, the past is being revised. Also the 'them' at the end may be ambiguous pointing to written records or alterations.
(B) Just as the present is changing, so too is the past constantly revised due to alterations and reinterpretations of written records
INCORRECT: One must use 'because of' or 'as a result of' when starting the sentence with 'the past is constantly revised'. Use of 'due to' is incorrect.
(C) Just like the constantly changing present, the past is being revised as a result of alterations to written records and reinterpretations of those records
INCORRECT. This is not better than E. Also it uses 'Just like the constantly changing present' and compares with the 'past' which 'is being revised' This comparison is not correct.

INCORRECT: One must use 'because of' or 'as a result of' when starting the sentence with 'the past is constantly revised'. Use of 'due to' is incorrect.

CORRECT. Although this sentence uses passive voice this is grammatically correct sentence. It correctly uses 'as a result of' rather than 'due to'. It also avoids pronoun ambiguity of option A, and conveys a clear meaning.
