Answer:
The answer is option (B) Foot-in-the-door phenomenon
Explanation:
Foot-in-the-door phenomenon is a technique of getting someone to grant or comply with a large request by initially making small or modest requests.
The technique is based on the logic that if a respondent (the person being asked) can grant an initial small or modest request, then the respondent would be most likely to later grant a larger request that he/she (the respondent) would not have granted if asked outright (without being approached with small requests first).
