The components of a vector are the parts of the vectors that are what to each other.

The components of a vector are the parts of the vectors that are Perpendicular to each other

Explanation:

As we know that two components of vectors are the two parts of the vector which on adding with each other gives total vector.

Here we know that when vector forms an angle with given direction then its two components are given as

So here in above case we say that if a vector A is at some angle then the two components are perpendicular to each other.

So here correct answer will be

The components of a vector are the parts of the vectors that are Perpendicular to each other
