Properties of an electric transformer

The above is a schematic diagram of an electric transformer, where the primary AC voltage is $220\text{ V}$and the secondary coil is connected with an electric heating instrument. The secondary voltage and current intensity are $110\text{ V}$and $8\text{ A},$respectively. Which of the following statements is correct?

There is no energy loss in this electric transformer.

$a)$The current intensity flowing in the primary winding is $4\text{ A}.$
$b)$The number of turns in the secondary winding is twice as many as that in the primary winding.
$c)$The primary coil always transfers $880\text{ W}$of electric power to the secondary coil without reference to any heating instrument.
