The reactance of a capacitor is given by:
\(X_c={1\over 2\pi fC} \)
For the DC source, f = 0
\(X_c={1\over 0} \)
\(X_c=∞\)
Since the reactance offered by the capacitor is ∞, hence the circuit acts as an open circuit.
Inductor
The reactance of an inductor is given by:
\(X_L=2\pi fL\)
XL = 0
Since the reactance offered by the inductor is 0, hence the circuit acts as a short circuit.
