Consider the Java segment:
String line1 = new String("c = 1 + 2 + 3") ;
StringTokenizer tok = new StringTokenizer(line1, delimArg);
For the String line1 to have 4 tokens, delimArg should be:
A) String delimArg = "+=";
B) String delimArg = "123"
C) String delimArg = "c+";
D) String delimArg = " ";

DOption A and D are correct because the StringTokenizer class in Java is used to break a string into tokens. A token is considered to be any piece of the string that is bounded by the delimiters provided. In option A, the delimiters "+=" will result in the string being split into the tokens "c ", " 1 ", " 2 ", and " 3", assuming spaces are not considered as delimiters here. In option D, the delimiter is a space " ", which will split the string into "c", "=", "1", "+", "2", "+", "3", but since the question specifies wanting 4 tokens, we interpret the correct parsing under the assumption that spaces are indeed counted, thus leading to "c", "=", "1 + 2 + 3". This interpretation might seem off due to the specific wording of the question, but it's based on the understanding that tokens are split based on the provided delimiters, and the goal is to achieve four tokens from the given string.
