Sir aap isme field and ring nahi karaoge kiya??

[@pitabashjena3284]

Sir (Q, +) is non cyclic and (R, +) also non cyclic. So option d is wrong

[@SoulShocker]

D is the correct option
Reason : Q is countable and R isnt countable. So, we can't make any bijective mapping from Q to R. Hence, No Isomorphism possible
