The charge on a parallel plate capacitor varies as \[q={{q}_{0}}\,\cos \,2\pi vt\]. The plates are very large and close together (area = A, separation = d). Neglecting the edge effects, the displacement current through the capacitor is

• A. \[2\pi v{{q}_{0}}\,\sin \,2\pi vt\]
• B. \[3/5\pi v{{q}_{0}}\,\sin \,\pi vt\]
• C. \[4\pi v{{q}_{0}}\,\sin \,2\pi vt\]
• D. None of these
