The Population of the world has magnitude but no direction. So the last option D is incorrect. If we look closely at the options the second option has option D with option A. Since option D is incorrect so option A too. Now remaining are options B and C. Option B is correct since the river has magnitude as well as direction Option C is also correct since the plane has magnitude and direction

Answer : Last option (b),(c)

The current of the river at a certain point is a vector. The current of the river is not "a" vector. The flight path is a path, and if it does not lie on a straight line, it cannot be a vector. So the answer is: none of the above.
