The correct answer is D) not manly.
Before he shots the mad dog, Jem and Scout believed that Atticus was not manly.
We are referring to an excerpt of “To Kill a Mockingbird”, written by Harper Lee in 1960.
Jem had never witnessed his father skills. He thought he knew everything there was to know about his father, Atticus. But the day he witnessed his father shot the mad dog in that complicated situation, his opinion changed. When Jem witnessed that scene, he was confused and perplex. He was surprised and he told Scout how impressed he was to see his father doing that and so quickly.
