What kind of question usually produces a wide variety of responses by allowing respondents to answer in whatever way seems appropriate to them? a closed-ended question an open-ended question a double-barreled question a leading question a loaded question?

An open ended question produces a wide variety of responses by allowing respondents to answer in whatever way seems appropriate to them.

Example: What do you think the film was trying to convey?

Closed: Did you like the film? ( either yes or no will be the response, or I don't know)
Leading: You liked the film, right?
Loaded: Did you have a nice time napping?
Double barreled: Did you enjoy the film and where we sat?

Yes i believe the answer is b. it seems to be the most logical answer. hope this . : )
