Option C uses the uniform initialization syntax introduced in C++ 11 to initialize the vector with the given values. Option A is incorrect because it uses angle brackets instead of curly braces for the initialization, which would be appropriate for specifying the size and default value of the vector. Option B is also correct, but it uses copy initialization syntax, which can be less efficient than the uniform initialization syntax. Option D is incorrect because it attempts to declare a variable named "vector n" with initializer lists for the values, which is not a valid syntax in C++.
