The correct option is B) Stone, Bronze, Iron
There are three ages: Stone Age, Bronze Age and Iron Age. These ages are divided chronologically according to the material with which tools were created: We have the Stone Age in first place since stone was used to make implements. This age is a pre historic period between 8700 and 2000 BCE. In the second place we have the Bronze Age, in which bronze was mainly used to create tools. During this age, early characteristics of urban civilization were found. And finally, we have the Iron Age. During this period, tools and weapons were made of carbon steel (ironworking).

This lead to the extintion of the dinosaurs who were not able to feed themselves as plants didn't grow. Photosynthesis was not possible and food chains could not be completed. When the dust settled the greenhouse gases were locked in the atmosphere causing a general increase of temperature.
