Two vectors \vec{P} and \vec{Q} has the same size but different direction as shown in the FIG. The correct statement regarding vectors \vec{P} and \vec{Q} is
a. \vec{P}\cdot\vec{Q}<\vec{P}\times\vec{Q}
b.\vec{P}\cdot\vec{Q}>\vec{P}\times\vec{Q}
c. \vec{P}\cdot\vec{Q}=\vec{P}\times\vec{Q}
d. \left|\vec{P}+\vec{Q}\right|<\left|\vec{P}-\vec{Q}\right|
e.\left|\vec{P}+\vec{Q}\right|>\left|\vec{P}-\vec{Q}\right|
