Which of the following statements is false for the angular momentum $$\overrightarrow L $$ about the origin ?

$$\overrightarrow L = mv\left[ {{R \over {\sqrt 2 }} + a} \right]\widehat k$$
when the particle is moving from B to C.

$$\overrightarrow L = {{mv} \over {\sqrt 2 }}R\widehat k$$
when the particle is moving from D to A.

$$\overrightarrow L = - {{mv} \over {\sqrt 2 }}R\widehat k$$
