Answer:
A. "bet on any thing".
Explanation:
Mark Twain's short story "The Notorious Jumping Frog of Calaveras County" is a retelling of a story that the narrator had heard from a bartender named Simon Wheeler. This story is about a frog who was believed to be the biggest jumper of all frogs.
The narrator had gone to the place to look or inquire about a friend's friend Leonidas W. Smiley. But once there, he couldn't get hold of the actual person, upon which the bartender offered to tell him a story about a guy named Jim Smiley. Simon also added that Jim "would bet on anything—the dangdest feller".
