The correct answer is B, a laminated core and a shading coil.
A key difference in an AC relay is the presence of a "shading coil". The purpose of this coil is to keep the relay on when the current drops to zero during phase change (note that in AC power the current and voltage are alternating in a sine wave around 50/60 times per second). The shading coil retains some magnetic energy and essentially holds the relay ON when the current drops to zero momentarily due to the AC waveform.
AC relays also have a laminated core to prevent losses due to eddy current heating.

Explanation:
A program is a set of ordered operations for a computer to do in computing. The program in the modern computer described by John von Neumann in 1945 has a one-at-a-time series of instructions that the computer follows. Typically, the application is saved in a computer-accessible storage location.
