IMO A. Pure case of Parallelism and all the clauses are set of by pair of commas so each individual clause should make a complete statement.
Things are parallel as:
Deborah Sampson,
1. joined the Continental Army
2. was injured three times (we can't remove "was" from this, it does not stands correct as an individual statement --> She injured three time (Wrong))
3. and was discharged in 1783 becayse (correct use of ",and"- used to join more than two clauses, also same explanation
