    Answer: (B) The study is an observational study.

    Step-by-step explanation:

    A study in which a researcher observe the behavior of the participants in a certain manner without interfering then is known as observational study. There is no control over the variables.

    On the other hand, In experimental study has control over one or more controlled factors to study the change in dependent factor.

    A survey that asks the opinions of students about a proposed tour program to a hill station is an observational study because there is no controlled factor.

    Every body has their own opinion with any dependence.
