I have doubt between A and D , Why not D? when do we need to use passive voice?

Dear itishree
Of course, this is OG13 SC #37. I'm happy to help.

First of all, we have the passive because the subject and theme of the sentence, Deborah Sampson, was the recipient of the action --- she received the injury: she didn't injure someone else. For more on when the passive voice is acceptable, see:

The deeper issue is parallelism. Choice (A) has correct parallelism:
....Deborah Sampson, the first woman to draw a soldier's pension,
//joined the Continental Army in 1782 at the age of 22,
//was injured three times,
and
//was discharged in 1783 because she had become too ill to serve

We have three full verbs in parallel, which is 100% correct. Choice (D) changes the full verb "was injured" to a participle. Now, in another sentence design, it could be perfectly correct to have participial phrase modifying the subject:
Deborah Sampson, injured three times, was a true war hero.
That's a perfectly correct sentence. The problem is not with the participle itself -- the problem is parallelism. We can't have verb//participle//verb --- that's not proper parallelism. That's why (A) is correct.

Does all this make sense?
