Which sentence below is not properly punctuated? a. she finished her work and then took a long lunch. b. i am typing a letter, and she is talking on the phone. c. mae said "why don't you come up and see me sometime? " select the best answer from the choices provided a b c

b. I am typing a letter, and she is talking on the phone.

Explanation:

The statement I am typing a letter, and she is talking on the phone is not properly punctuated and reason being that the comma(,) before the 'and' word should not be there since 'and' already serve as a conjunction and what conjunction does is to combine two statements together in a sentence. The comma that is present there is creating a pause while reading the sentence which is not suppose to be so because the presence of 'and' word there will cause the sentence to be pronounced at once without any pause.

The correct punctuation is - I am typing a letter and she is talking on the phone.
