Answer:

Option (C)

Explanation:

Migmatite can be defined as metamorphic rock that is formed at high pressure and temperature condition, depicting pro-grade type of metamorphism. This rock is formed from the partial melting of unaltered minerals or those minerals that are slightly modified. But in this process of formation, the bulk mass of the rock remains consistent. It is a transitional rock between the igneous and the metamorphic rock.

Thus, the correct answer is option (C).

There are time delays due to the amplifiers and repeaters required in the path, and due to the fact that the signals don't actually travel at the speed of light in a wire.

A test of internet speed between Seattle and Washington, DC shows a round-trip time of about 87 ms when traffic is light. Modern communication channels tend to be faster than the telegraph (especially when measured in words per minute).
