What happens to the direction and magnitude of a vector when it is multiplied by a positive and a negative scalar $\lambda$?

• A
  Positive $\lambda$: Same direction,magnitude scaled by $\lambda$; Negative $\lambda$: Opposite direction,magnitude scaled by $|\lambda|$.
• B
  Positive $\lambda$: Opposite direction,magnitude scaled by $\lambda$; Negative $\lambda$: Same direction,magnitude scaled by $|\lambda|$.
• C
  Positive $\lambda$: Same direction,magnitude remains same; Negative $\lambda$: Opposite direction,magnitude remains same.
• D
  Positive $\lambda$: Opposite direction,magnitude scaled by $\lambda$; Negative $\lambda$: Opposite direction,magnitude scaled by $|\lambda|$.
