Read the following text and answer the following questions on the basis of the same:
Electric Toaster : Small Industries Service Institute Takyelpat Industrial Estate Imphal has designed an Electric toaster which is operated at 220 volts A.C., single phase and available in four different rated capacity such as 600 W, 750 W, 1000 W and 1250 W. The heating element is made of nichrome 80/20 (80% nickel, 20% chromium), since Nichrome does not get oxidise readily at high temperature and have higher resistivity, so it produces more heat.
The element, is wound separately on Mica sheets and fitted with body of toaster with the help of ceramic terminals.
Operating voltage of the device is:

Options

A. 220 V AC, single phase
B. 220 V AC, three phase
C. 220 V DC
D. 220 V AC/DC
