Which of the following statements is TRUE about the regular expression 01*0?

The regular expression 01*0 matches strings that start with '0', followed by zero or more '1's, and end with '0'. This generates strings like '00', '010', '0110', etc. The number of such strings is infinite because the middle part can have any number of '1's, but each individual string is finite in length. Therefore, it represents an infinite set of finite strings, making option B correct.
