You have touched my weakest spot with this Question
But I can't claim the credit to answer it correctly as I have seen it numerous times.
The principal difficulty faced in these type of question is getting the components of the main list and sub list
For example, the below sentence has 3 events.
1) turned the tide of English victories in her country
2) liberating the city of Orleans
3) persuaded Charles VII of France to claim his throne
Thankfully this Q has only last one underlined. But can't expect Q to lucky each time. right...
Anyway, 2) is dependent on 1). Hence 2) is modifier.
1) and 3) seem to independent, hence should be made parallel. (Toughest step to decipher in other Qs, at least for me)
Once we know the above the other things will become easy.
Q for reference

Error Analysis
---------------------
Since, (1) should be parallel to (3)
Errors:
a) she not reqd
b) should start with persuaded
POE
---------
between B & D, B seems to change the meaning (it seems to suggest that persuasion is not done to claim the throne, rather for claiming it)
Hence D seems to be the best one out of the lot.
