To add an element to a vector of integers named numbers at the next available position in the vector, you would use:

Option D is correct because the correct syntax to add an element to a vector at the next available position is to use the push_back() function. This function adds the element to the end of the vector, increasing its size by 1. Option A is incorrect because it attempts to access an index that does not exist in the vector. Option B is incorrect because it attempts to assign a value to the entire vector, which is not valid. Option C is incorrect because it uses an incorrect function name and syntax.
