The answer is 4d. According to Bohr bury principle the value of the summation of 4d and 6s orbitals are same. So we have to consider the principle quantum number instead of the summation. So as the 4d orbital has less principal quantum number than the 6s orbital,it has a less energy. Accord to aufbau principle the electron will occur the 4d orbital first.
