The pattern of figures \triangle\ \bullet\ \square\ \blacktriangle\ \bigcirc is repeated in the sequence \triangle, \bullet, \square, \blacktriangle, \bigcirc, \triangle, \bullet, \square, \blacktriangle, \bigcirc, \ldots\ . The 214th figure in the sequence is

\textbf{(A)}\ \triangle\quad \textbf{(B)}\ \bullet\quad \textbf{(C)}\ \square\quad \textbf{(D)}\ \blacktriangle\quad \textbf{(E)}\ \bigcirc
