(a) different metal expand due to higher temperature because due to movement of particles they have need more space , then hole increase

Metals expand when you heat them, so the circle should expand. There's no real difference between the circle and a hole (of the same size) cut out of it. The circle is, in effect, the circumference of the hole you put into it. So the hole will get larger.
