Answer:
None of the them has a complete answer
.
Explanation:
The current in a wire is a function of the conduction element geometry inside the cable, given by the resistance and the conduction area. So saying twisted/shield, is not giving us any information about the current rating of the wire.
Repairs to the wire may affect the area of the conductor, reducing the effective surface of conduction. But a well-executed repairing must made an insignificant change in the resistance. So it's not a definitive concept.
A twisted/shield wire is generally used for signal transport, as it's configured to reduce the noise in the data transmission.

Answer:
Option (D) By observing illuminated mountain peaks in the dark portion of the moon.
Explanation:
Unlike the traditions at the time of Aristotle which considered that the celestial bodies are spherical and perfectly smooth bodies.
But based on Galileo's observations, the zone that was illuminated in the dark region of the moon near the line that separates the illuminated and the shadowy parts, known as terminator was noticed.
On the breaking of the dawn, as the sunlight hit the top of the lunar mountains it lightens up while the valleys are still dark.
Roemer used the diameter of the earth's orbit in his calculation of the speed of light.
