Match the List -I and List-II and select the correct set from the following sets given below:
`{:((A)." The number of sub-energy levels in an energy level",(1)." "n^(2)),((B)." The number of orbitals in a sub-energy level",(2)." "3d),((C)." The number of orbitals in an energy level",(3)." "2l+1),((D)." n=3,l=2,m=0",(4)." "n):}`

Options

A. `{:((A),(B),"(C)","(D)"),("4","3","1","2"):}`
B. `{:((A),(B),(C),(D)"),(3,1,2,4):}`
C. `{:((A),(B),(C),(D)"),(1,2,3,4):}`
D. `{:((A),(B),(C),(D)"),(3,4,1,2):}`

Answer

A

Explanation

Number of orbitals in a shell `=n^(2)`
Number of subshell in a shell=n
Number of orbitals in a subshell=(2l+l)
n=3,l=2,m=0 represents 3d
