Explanation:

An observational study is one where researchers observe and measure variables without applying any treatment or intervention. In this case, the study measures children’s growth rates without treating them, so it fits the definition of an observational study. A simple random sample is a sampling method, not a study type. Discrete data is a type of data, not a study classification. An experiment involves applying a treatment, which is not done here.
