Question

Which of the following statements is correct regarding transformers?

Answer 1

Answer:

C. If an alternating current is present in the primary coil, a current will be induced in the secondary coil.

Explanation:

As we know by the principle of induction given by faraday there will be induced EMF in the coil if the magnetic flux linked with the coil will change with time.

$E = -\frac{d\phi}{dt}$

now we know that when alternating current passes through the primary coil then it will change the flux linked with the secondary coil.

Due to change in the flux of secondary coil it will induce the EMF in that coil.

so here correct answer will be

C. If an alternating current is present in the primary coil, a current will be induced in the secondary coil.

Answer 2

Wow !  The wording here seems so complicated that even an
electric current might have a hard time finding its way through
these statements.

if I haven't been tricked by all this complexity, bloviation, and
obfuscation, then Choice-C is the best one.
