Together, the spindle fibers from either centriole guide the chromosome to the center of the mitotic spindle. This stage of mitosis is called metaphase and the arrangement of chromosomes lined up in the center of the mitotic spindle is referred to as the metaphase plate.

Option (4)
Explanation:
The earth is comprised of numerous lithospheric plates. This lithosphere is comprised of dozens of major plates and a few minor plates. These plates are constantly in motion over the less dense asthenosphere layer where the rocks tend to flow during deformation. This plate motion takes place due to the creation of convection current in the mantle region as a result of which the plates move under the influence of uprising magma. These currents are formed because of the heat supplied from the core of the earth.
Some of the major plates are Indo-Australian plate, North American Plate, South American plate and the Pacific plate.
Some of the minor plates include the Cocos plate, Nazca plate, and Caribbean plate.
Thus, the correct answer is option (4).
