The difference is that apart from the capital letters for QUESTION, there is a space after the colon with zero or more spaces behind it...

So, try:
Code:
awk -F'[.,:] *' '         # Use dot, command and colon as fields separator
  /^[A-E]\./ {            # Store the choices in array A with index the first field (letter A-E)
    i=$1
    $1=x
    A[i]=$0
  }
  /^Answer/ {             # If line starts with "Answer" then print the valid choices
    for(i=2; i<=NF; i++)
      print $i"." A[$i]
    print x               # Print an empty line
  }
  /^QUESTION/             # If line starts with "QUESTION" then print the question
' file

Thank you very much again sir. It is working fine now. However, when one answer has multiple lines, for example:

Code:
A. [edit schedulers] 
user@host# show 
scheduler no-weekends { 
daily all-day; 
sunday exclude; 
saturday exclude; 
}

the script output is only the first line:

Code:
A. [edit schedulers]

How can I show the entire lines for that answer?

Alright, but the input specification keeps changing, are you sure this is that last exception?

Try:

Code:
awk -F'[.,:] *' '         # Use dot, command and colon as fields separator
  /^[A-E]\./ {            # Store the choices in array A with index the first field (letter A-E)
    i=$1
    $1=x
    A[i]=$0
    choice=1
    next
  }
  choice {
    A[i]=A[i] RS $0
  }
  /^Answer/{             # If line starts with "Answer" then print the valid choices
    choice=0
    for(i=2; i<=NF; i++)
      print $i"." A[$i]
    print x               # Print an empty line
  }
  /^QUESTION/             # If line starts with "QUESTION" then print the question
'  file
