If ` vec a`and ` vec b`are two collinear vectors, then which of the following are incorrect:(A) ` vec b=lambda vec a ,`for some scalar lambda (B) ` vec a=+- vec b` (C) the respective components of ` vec a`and ` vec b`are proportional (D) both the vectors `vec a` and `vec b ` have same direction, but different magnitudes.

Explanation

To solve the problem, we need to analyze the properties of collinear vectors and determine which of the given options is incorrect.

### Step-by-Step Solution:

1. **Understanding Collinear Vectors**:
- Two vectors \(\vec{a}\) and \(\vec{b}\) are said to be collinear if they lie along the same line. This means that one vector can be expressed as a scalar multiple of the other. Mathematically, this can be expressed as:
\[
\vec{a} = \lambda \vec{b}
