please answer. thanks!

Imagine that you have arrived in Malate, Manila to conduct a case study on working street children. A local social worker introduces you to two former street working children and you learn that they still have lots of friends still working on the street. As a way to identify participants for your study, you ask the two former street working children if they can recommend and invite some of their friends on the street to participate in the study. You also ask them to spread word of the study in anticipation that their friends will also help you to identify potential participants. How would you classify this kind of sampling? 1. Quota sampling? 2. Snowball sampling? 3. Random purposeful sampling? Explain your answer.
