Thank you
sayantanc2k for the question!!!
A. the faulty load bearing mechanisms unable to damp down its vibrational energy, and was
CORRECT. The statement as is is correct. It correctly uses an absolute phrase "he faulty load bearing mechanisms unable to damp down its vibrational energy" to modify the entire preceding clause. There is no SVA errors in the sentence, and modifiers are placed correctly.
B. unable to damp down its vibrational energy by the faulty load bearing mechanisms and
INCORRECT. This sentence seems to be convey the non sensical meaning that the bridge itself was unable to damp down its vibrational energy. Use of passive voice is awkward.
C. the faulty load bearing mechanisms were unable to damp down its vibrational energy and were
INCORRECT. Use of were in "the faulty load bearing mechanisms were unable to damp down its vibrational energy" is incorrect. This has to be a modifier modifying the preceding clause: "The bridge oscillated vigorously under the fluctuating load of the oncoming vehicles". Also use of 'were' leads to a glaring SVA error.
D. it was unable to damp down its vibrational energy by the faulty load bearing mechanisms and was
INCORRECT. Same issue as in B. Also, two clauses are incorrectly joined by a comma
E. the faulty load bearing mechanisms were unable to damp down its vibrational energy, was
INCORRECT. If this were to be a list of clause there had to be a need of and an subject in the 3rd element of the list. This is not parallel.
Also the sentence connects two independent clauses with comma.
