If 'gnr tag zog qmp' stands for 'seoul olympic organizing committee', 'hyto gnr emf' stands for 'summer olympic games' and 'esm sdr hyto' stands for 'modern games history', what would be the code for 'summer'?

S1:

'gnr tag zog qmp' == 'seoul olympic organizing committee'

S2:

'hyto gnr emf'== 'summer olympic games'.

So, from S1 and S2 we can say that ,

Olympic = gnr. (as gnr is common to S1 and S2 as well as Olympic)

Now,

S3:

'esm sdr hyto'== 'modern games history'.

So, from S2 and S3 we can say that :

Games=hyto(as both are common to S2 and S3)

So, if we mark out games and olympic from S2 ,we get Summer=emf.

A is correct choice.
