SQL SERVER SCRIPT - NESTED IF STATEMENTS

I am attempting to figure out a SQL script and am unclear how nested IF statements behave. An example of what I am trying to figure out is shown below. Assuming that the 1st IF statement is true (A='22222'), does the last IF statement (IF D = 'ORTGNV')  get evaluated regardless of the answer to the second IF statement (IF B='12345' and C='98765')? I've also attached a word copy of the script in case indentation is messed up.

IF A = ‘22222’
      BEGIN
            DO AAA
            IF B = ‘12345’ and C = ‘98765’
                  BEGIN
                        DO BBB
                  END
            ELSE
                  BEGIN
                        DO CCC
                  END
            IF D = ‘ORTGNV’
                  BEGIN
                        DO DDD
                  END
END
