Which of the following statements is false?

C++14's global rbegin, rend, crbegin and crend functions are for iterating through a built-in array or a container
from back to front.
b. Functions rbegin and rend return iterators that can be used to modify data, and rcbegin and rcend return const
iterators that cannot be used to modify data.
c. Functions begin and end and their C++14 const and reverse versions may also receive container objects as
arguments—each function calls the corresponding member function in its container argument.
d. When iterating using iterators, it’s common for the loop-continuation condition to test whether the iterator has
reached the end of the built-in array or the container. This technique is used by many Standard Library algorithms.

b. Functions rbegin and rend return iterators that can be used to modify data, and rcbegin and rcend return const
iterators that cannot be used to modify data.
