When a wire is stretched, its resistance typically increases. This is because stretching the wire increases its length and reduces its cross-sectional area, which in turn increases the resistance of the wire.

In this case, the resistance of the wire is initially given as 10 Ohm. If the wire is stretched by a factor of ten, we can expect the resistance to increase by the same factor.

Multiplying 10 Ohm by 10 gives us 100 Ohm, and multiplying 100 Ohm by 10 again gives us 1000 Ohm.

Therefore, the correct answer is option 4, which states that if the wire is stretched ten times, the resistance will be 1000 Ohm.

Alert - correct answer should be option 3: 100 Ohm.
