Given below are two statements: Statement I: The vector equation of line passing through two points with position vector \(\vec{a}\) and \(\vec{b}\) is \(\vec{r} = \vec{a} +\lambda(\vec{b}+\vec{a})\) Statement II: The vector equation of a straight line passing through a fixed point with position vector \(\vec{a}\) and parallel to a given vector \(\vec{b}\) is \(\vec{r}=\vec{a}+λ\vec{b}\) where λ is scalar. In the light of the above Statements, choose the most appropriate answer from the options given below :
