Vba multiple condition

Hi,

I have created a VBA with the condition whereby if the nos are greater than/equal than 31 and less than/equal to 46, the value will return 1 in column L.

But now, I want to add another condition whereby this will only be apply if column D is AA. Can anyone assist me on how to add that condition below?

Sub macros()

Dim lRow As Long

Sheets("COMVERSE").Select

lRow = Range("I" & Rows.Count).End(xlUp).Row

For i = 2 To lRow

    
     If Cells(i, 9) >= 31 And Cells(i, 9) <= 46 Then
        Cells(i, 12) = "1"
    Else
        Cells(i, 12) = "NO"
    End If
    

Next i

End Sub
