Some waveforms among I, II, III and IV superpose to produce waveforms P, Q, R and S. Match the resultant waveforms with the corresponding superpositions.

A

$$ P \leftrightarrow O, Q \leftrightarrow N, R \leftrightarrow L, S \leftrightarrow M $$

B

$$ P \leftrightarrow M, Q \leftrightarrow N, R \leftrightarrow L, S \leftrightarrow K $$

C

$$ P \leftrightarrow M, Q \leftrightarrow N, R \leftrightarrow K, S \leftrightarrow L $$

D

$$ P \leftrightarrow O, Q \leftrightarrow  M, R \leftrightarrow L, S \leftrightarrow K $$
