In a certain code language, ‘Flames are bright’ is written as ‘@ # %’ and ‘Bright is sun flames’ is written as ‘* # 7 @’. Which one of the following is the possible code for ‘is’ in that code language?

*

Given; In a certain code language, ‘Flames are bright’ is written as ‘@ # %’ and ‘Bright is sun flames’ is written as ‘* # 7 @’.

So,

Flames  are  bright  =  @  #  %

Bright  is  sun Flames  =  *  #  7  @

Thus,

are is coded as %, either 'is' or 'sun' is coded as * or 7

either Flames or Bright is coded as @ or %

But, 7 is not given 

Therefore, now 'is' is coded as *
