Which sentence does not contain any errors in comma usage? a. by the way i found your missing, leather gloves. b. on the contrary, she loves to eat frogs' legs. c. this pen for instance, has green ink. d. it's about six o'clock i guess.

The answer is B. On the contrary, she loves to eat frogs' legs.

Reason, in A there shouldn't be a comma after missing. I doesn't make sense, the comma should be after By the way, I found your missing leather gloves.

Reason, in C. there should be a comma after pen. This pen, for instance, has green ink.

Reason, in D. there should be a comma after clock. It's about six o'clock, I guess.

Hope this helps. :)

it is the : d because is true

what are the choices?
