Final answer:
The true statement is that there is a lithospheric plate called the Eurasian Plate. The other names do not correspond to recognized lithospheric plates. So the correct option is C.
Step-by-step explanation:
The question pertains to the topic of plate tectonics and lithospheric plates, which are both crucial in understanding Earth's geology. These plates consist of the Earth's crust and the uppermost rigid portion of the mantle, together termed the lithosphere. Among the given options, there is indeed a lithospheric plate named the Eurasian Plate, which encompasses Europe and Asia. On the other hand, there is no known plate called the Triassic, Tectonical, or Mikasa Plates. The Triassic refers to a geological time period, and the other names don’t correspond to recognized plates.
