In which arduino board?

You can't select any pins for hardware Serial interface other than predefined 0 & 1. But you can create additional software-based serial port.
Read the documentation for SoftwareSerial library

#include <SoftwareSerial.h>

SoftwareSerial mySerial(A0, A1); // RX, TX

void setup()
{
  // set the data rate for the SoftwareSerial port
  mySerial.begin(38400);
  mySerial.println("Hello, world?");
}

void loop() {}

Thanks. That's what I wanted to know, mySerial(A0, A1); // RX, TX
