It is false that the connotations of a word have little effect on its literal meaning. Connotation are your personal feelings that a certain word evokes when you think about it/read it/write it.
For example, the word home means a house, but its connotation is usually positive - you connect it with love, warmth, etc.
Question already asked before :)

The answer would be letters A and B."
