Parallel structure tests entities in a list which is identified by a marker and the list should talk about a common topic.
Here the marker is “and” and the entities are:
turned the tide of English victories in her country by liberating the city of Orleans
she persuaded Charles VII of France to claim his throne
Both the entities talk about what Joan of Arc did. Both should be parallel.
"She" is redundant, Eliminate A
“Turned” is parallel to “persuaded”, eliminate C and E
Between B and D
“to claim” is the correct idiom. D wins
