Answer:
a. providing child care
Step-by-step explanation:
Manifest functions are those that are intended functions of a particular society. For example, the manifest function of schools is to educate children, which means that as society, this is the reason why we have created schools. Latent functions are the ones that are not intended, but that still happen. In this case, child care is intended to provide "care" for children (manifest). However, as an unintended product, it also provides education (latent).
