What types of anthropologists explore all aspects of living human culture—from war and violence to love, sexuality, and child rearing—and look at the meanings that people from all over the world place on these things?

The correct answer is cultural anthropologists. 

Cultural anthropologists primarily investigate various aspects of human culture, societies they live in, and the growth of societies. Cultural anthropologists are interested in the history of society and culture, and how they both have evolved and developed over time. This branch of anthropology is also concerned with the differences between the various cultures and societies across the globe.
