answer : D A canonical pathname is both absolute and unique. That means it includes getting absolute path and no removing redundant names (normalization). ABC doesn't include both those operations. D includes it with file.getCanonicalPath();

Selected Answer: D

D is correct The file object is created using the filename variable.The getCanonicalPath() method is called on the file object to get the canonical path of the file.The canonicalPath variable is then used to create a new FileInputStream object. This code will ensure that the path name is validated and canonicalized before the file is read.
