Answer:
probably the first one or second. not sure, sorry.
Step-by-step explanation:
Abraham Lincoln was triumphed by Douglas, losing the debate, but his debate was very well done, earning him recognition and such.
The third option though, "he had married a wealthy widow" just doesn't add up and isn't neccisarly reasonable to become a rising star in the republican party.
Being a skilled fighter and a well known debater however, does earn a role.
Hope this helped, sorry if it didn't :(
