A vector changes if
1. Any of these
2. its direction changes.
3. its direction and magnitude both change.
4. its magnitude changes.
5. None of these

Answer :

vector is described as a quantity that have both direction and magnitude

A vector will change if : 
- It's direction and magnitude both change
- It's direction change
- It's magnitude change

So i guess the asnwer will be 1. any of these

Hope this helps

A vector changes if 1. Any of these

Further explanation

A vector is a mathematical object that has a size, called the magnitude, and a direction. A vector consists of a magnitude and direction. If either, or both change, the vector is changed. So a vector changes if its direction changes, its direction and magnitude both change and its magnitude changes.

Vector quantities are are usually drawn as pointed arrows with the length of which represents the vector's magnitude. The scaled vector diagrams which depict a vector by use of an arrow drawn to scale in a specific direction. The magnitude of a vector is depicted by the length of the arrow. The arrow is drawn a precise length in accordance with a chosen scale as shown in the picture below.  Note that moving the vector around doesn't change the vector, as the position of the vector doesn't affect the magnitude or the direction. Most commonly in physics, vectors are used to represent displacement, velocity, and acceleration. A vector is a scalar with direction. Some examples of vector quantities are force, velocity, acceleration, displacement, and momentum.
