Function templates

a. are overloaded automatically

b. can be overloaded

c. are never overloaded

d. can be overloaded, but seldom are in common programming practice

Option B. can be overloaded

Explanation:

These functions can be overloaded, it means that  we can have functions with the same name as long as the types or the number or the arguments are different.  A function template can be overloaded in two ways: with other function templates or with normal functions.

A normal function has not relation to a function template, it is not considered an specialization.
