If the principle quantum number n = 6, the correct sequence of filling of electron will be :
ns→(n−1)f→np→(n−2)
ns→(n−2)f→ np →(n−1)
ns→(n−2)f→(n−1)d→np
ns→np→(n−1)d→(n−2)f
A
ns→(n−2)f→ np →(n−1)
B
ns→np→(n−1)d→(n−2)f
C
ns→(n−2)f→(n−1)d→np
D
ns→(n−1)f→np→(n−2)

If the principle quantum number n = 6, the correct sequence of filling of electron will be ns→(n−2)f→(n−1)d→np.
Here, n=6. Hence, the correct sequence of filling of electron will be 6s→4f→5d→6p.
