The question has the following values. R = 10 ohms Z = 20 ohms Since it is a series L-C-R circuit and the current and voltage are in the same phase as the circuit contains only resistance phase difference will be (a) Zero.
In case of resistance, the angle between current and voltage is zero

Answer:60°
Explanation:since cos$=R/Z , R being the resistance and Z the impedance
Cos$=10/20=1/2
Cos$=Cos60°
$=60°
