The answer to this question is option (C). C-String is not assigned value correctly.

Explanation:

This is because the size with which c-string is initialized is 7 and we are providing a string of 7 characters to store So there is no space left to store the null character '/0'. We can only store a string of size 6 in the c string. There is no need to provide the size in the string object as it is handled by string class.
