first of all i will say that verb-ed form is either acts as a verb or as a modifier
verb-ed -->this will act as a verb when subject itself does this (verb-ed thing) action ex: alex played well ....here played is acting as verb
verb-ed--->this will act as a modifier when this (verb-ed thing) is not done by the subject.
now coming to question
here the subject is Deborah Sampson
in the non underlined part it is written Deborah Sampson joined......here "joined" acts as a verb
in the underlined part it is written Deborah Sampson...was injured .....,and was discharged....so its list kind of thing x,y,and z therefore x,y,z should be parallel
..now----- joined ,was injured ,and was discharged are all verb so its parallel....
note if in place of was injured....only injured is written and in place of " was discharged "only discharged is written then in that case discharged and injured act as modifier as in option C,D,E.....HENCE it is not parallel to JOINED .....so it is wrong
now choosing answer
(A) 22, was injured three times, and was discharged in 1783 because she had become(parallel so correct)
(B) 22, was injured three times, while being discharged in 1783 because she had become( meaning is wrong ..in this it means she was injured and discharged simultaneously...which is not the intended meaning)
(C) 22 and was injured three times, and
discharged in 1783, being(...here joined ,was injured are verb while discharged is modifier so non parallel therefore incorrect)
(D) 22,
injured three times, and was discharged in 1783 because she was(again injured is not parallel.....so incorrect)
(E) 22, having been injured three times and discharged in 1783, being( againg discharged is modifier and not verb ,...and therefore not parallel....also it means having been injured and discharged ..both actions are occuring together which is not correct.
hope it helps..
