The vector function that is used to insert an item into a vector is `push_back()`. This function adds an element to the end of the vector and automatically resizes the container to accommodate the new element. Option A, insert_item, sounds like it could be a function used to insert an item but it is not a pre-defined function in the vector library. Option B, add_item, is not a defined function in the vector library. Option C, store, is not a pre-defined function in the vector library that is used for inserting elements.
