i think its answer should be Option B i.e. undeletable 
files because user use sticky bit with its files for the  
the purpose of security of its files and no one from outside can delete it

The bit in the mode of a Unix file which, if set for an executable, tells the kernel to keep the code loaded in swap space even after it has finished executing on the assumption that it is likely to be used again soon. This performance optimisation was included in some early (and recent) versions of Unix to save reloading frequently used programs such as the shell or vi from disk.If the sticky bit is set on a directory, an unprivileged user may not delete or rename files of other users in that directory even if he has write access to the directory.

The sticky bit was introduced in the Fifth Edition of Unix in 1974 for use with pure executable files. When set, it instructed the operating system to retain the text segment of the program in swap space after the process exited. This speeded subsequent executions by allowing the kernel to make a single operation of moving the program from swap to real memory

Hence the answer is A .Kernel
