Recall the definition of a vector: a quantity that has both magnitude and direction.
Recall the definition of a scalar: a quantity that has only magnitude and no direction.
Identify that the notation with an arrow over a letter, such as \(\vec{b}\) or \(\vec{d}\), typically represents a vector quantity.
Since both \(\vec{b}\) and \(\vec{d}\) have arrows over them, they both represent vectors, meaning they have both magnitude and direction.
Therefore, the true statement is that both \(\vec{b}\) and \(\vec{d}\) have both magnitude and direction.
