What first name starts with the letter F?

The first name that starts with the letter F is Frank. This choice directly meets the criteria outlined in the question, as it is the only option that begins with the specified letter. In contrast, the other options—Charlie, Baker, and David—begin with the letters C, B, and D, respectively. Understanding the requirement for the first name to start with the letter F helps to identify Frank as the correct answer. This type of question often tests not only the recognition of names but also attention to detail in identifying specific characteristics, such as initial letters.
