D-Erythrose

D-Erythrose and its isomers are listed as P, Q, R, and S in Column-I. Choose the correct relationship of P, Q, R, and S with D-erythrose from Column II.

(A) P \(\rightarrow\) 2, Q \(\rightarrow\) 3, R \(\rightarrow\) 2, S \(\rightarrow\) 2 

(B) P \(\rightarrow\) 3, Q \(\rightarrow\) 1, R \(\rightarrow\) 1, S \(\rightarrow\) 2 

(C) P \(\rightarrow\) 2, Q \(\rightarrow\) 1, R \(\rightarrow\) 1, S \(\rightarrow\) 3 

(D) P \(\rightarrow\) 2, Q \(\rightarrow\) 3, R \(\rightarrow\) 3, S \(\rightarrow\) 1

Answer 1

(C) P \(\rightarrow\) 2, Q \(\rightarrow\) 1, R \(\rightarrow\) 1, S \(\rightarrow\) 3
