A. a strain of houseflies resistant to insecticides emerges
B. squirrels separated by a river are found to be unable to interbreed
C. a son is born with a portion of his right index finger missing, the same portion severed from his father's hand in an accident
D. a strain of houseflies resistant to insecticides emerges; and squirrels separated by a river are found to be unable to interbreed
E. a strain of houseflies resistant to insecticides emerges; squirrels separated by a river are found to be unable to interbreed; and a son is born with a portion of his right index finger missing, the same portion cut off from his father's hand in an accident
 
C. a son is born with a portion of his right index finger missing, the same portion severed from his father's hand in an accident

that is the answer because over the father's lifetime, he acquired the trait of the lost finger. the son supposedly inherited the trait, or so Lamarck would have reasoned. obviously, since then, science has progressed to know that wouldn't be possible.
