Solution 1
A physical quantity which has magnitude but no direction is scalar and quantity which has both magnitude and direction is called vector.
The direction is represented by angle or with reference to the point of east. From the given options, (B), (C) and (D) have magnitude and direction. These are vector quantities.
Hence, option (B), (C) and (D) are incorrect answers.
The scalar quantity has magnitude but no direction.
Hence, the option 
is the correct answer.
