For any two vectors \(\vec{a}\) and \(\vec{b}\), which of the following statements is always true?

\(\vec{a} \cdot \vec{b} \geq|\vec{a}||\vec{b}|\)

\(\quad \vec{a} \cdot \vec{b}=|\vec{a}||\vec{b}|\)

\(\overrightarrow{\mathrm{a}} \cdot \overrightarrow{\mathrm{b}} \leq|\overrightarrow{\mathrm{a}}||\overrightarrow{\mathrm{b}}|\)

\(\quad \vec{a} \cdot \vec{b}<|\vec{a}||\vec{b}|\)
