Rohan is a salesman who in order to sell the soaps produced by his company, he goes door to door. He usually begins by making a small request first that the other person is not likely to refuse such as, 'May I have some water? Once the other person carries out the request, a bigger request is made such as "Would you want to buy our organic, skin safe soap set?". Simply because the other person has already complied with smaller request, s/he feels uncomfortable refusing the second request. This strategy of compliance is known as -

The foot in the door technique

The correct answer is Option (4) → The foot in the door technique

The foot-in-the-door technique is a compliance strategy where a person first makes a small request that is likely to be accepted, followed by a larger request. The idea is that once someone agrees to the smaller request, they are more likely to agree to the larger one due to a sense of consistency or obligation.
