3) In paragraph 12 Mrs. Bullfrog's harsh words for the driver who caused the carriage to topple over, and her smacking him twice on the ears,
reveal that
A) she is really unsure of me.
B)
she is not quite the refined lady she appears to be.
C)
she is someone who is easily cowed by the men
around her
D)
she is so refined that she is often scared of
confrontation

I believe the answer is A:

A) she is really unsure of me.

never read it so if i had i would definitely you sorry.

i believe it is the first choice (1.)

because the major theme is(“both the wild and civilization have rules.”)

and also as u said,( based on what buck learns within the call of the wild, "both the wild and civilization have rules".this is true of humans within society as well.
