If $\vec{a} = t \vec{b}$ where $t < 0$ is a scalar,then

• A
  $\vec{a}, \vec{b}$ are like vectors and $|\vec{a}| > |\vec{b}|$
• B
  $\vec{a}, \vec{b}$ are unlike vectors and $|\vec{a}| > |\vec{b}|$
• C
  $\vec{a}, \vec{b}$ are like vectors and $|\vec{a}| < |\vec{b}|$
• D
  $\vec{a}, \vec{b}$ are unlike vectors and either $|\vec{a}| \geq |\vec{b}|$ or $|\vec{a}| < |\vec{b}|$
