An option statement is special; it is used to embellish or describe questions.
These statements can be used to give the possible value and set the default
value for questions. In other words, they are not questions, but they influence
the questions they embellish. Therefore, the options' flags are treated as
question flags and can accept all values of question flags.
Options with the DEFAULT flags can be used to set the default value for questions.
