Answer:

A. 14

Explanation:

the researcher claims that the width of the interval would have been smaller if the sample had been different, and in this case different refers to larger. The original sample included only 15 people, so in order to increase the data sample, you must include more than 15 people. That is why 14 doesn't make sense.
