Answer:

(B)

Explanation:

Each winding of a transformer has a certain number of turns of wire.

The turns ratio is defined as ratio of turns of wire in the primary winding to the number of turns of wire in the secondary winding.

#"Turns ratio"="Number of turns in the primary coil"/"Number of turns in the secondary coil"=N_P/ N_S#

For the given values

#10=N_P/ N_S#
#=>N_S=N_P/10#

Sometimes "Turns ratios" states the voltage multiplication factor of the transformer.

In such a case
#"Turns ratio"=N_S/N_P#
#:.# (C) is the correct choice.

As it is not clearly mentioned in the question, hence, (B) is appropriate choice.
