• A. ingeniously; incredible
• B. ingeniously; incredulous
• C. ingenuously; incredible
• D. ingenuously; incredulous
  \bigskip

Hint:

“Ingenious” implies cleverness; “ingenuous” implies innocence. Pay close attention to nuanced vocabulary differences.

Answer 1

The Correct Option is A

The correct pair of words must convey that the leader used cleverness to refute the arguments and that his survival was almost unbelievable.
Ingeniously means cleverly or skillfully, which fits the action of refuting claims. Incredible refers to something unbelievable — a good fit for describing extraordinary luck.
“Ingenuously” means naïvely or innocently, which does not fit the context of a strategic refutation. \[ \boxed{\text{ingeniously; incredible}} \] \bigskip
