Explanation:

Archaeopteryx is an iconic fossil bird that lived during the Late Jurassic, approximately 150 million years ago. Archaeopteryx is iconic because it is a transitional fossil between non-avian dinosaurs (reptiles) and birds. The osteology of Archaeopteryx indicates that it was similar to that of nonavian theropod dinosaurs, i.e.,  dinosaurs characterized by hollow bones and three-toed limbs. Unlike modern birds, Archaeopteryx had a full set of teeth, a long tail, three fingers with claws and hyperextensible second toes commonly known as 'killing claws'.

c. live where it’s cold and icy

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
