Consider the following partial class with constructor: public class Filename {
private String fullPath;
private char pathSeparator,
extensionSeparator;

public Filename(String str, char sep, char ext) {
fullPath = str;
pathSeparator = sep;
extensionSeparator = ext;
}

Which statement could be used to create an object of the Filename class?

a. Filename myHomePage = new Filename(FPATH, '/', '.');
b. Filename myHomePage = new Filename();
c. Filename myHomePage = new Filename(FPATH);
