C Correct answer
Explanation

Leeuwenhoek first saw and described a living cell. Mitochondria was first observed by Kolliker in 1850 as granular structure in striated muscles. Endoplasmic reticulum was discovered by Porter and Thompson in 1945 and was named in 1953 by Porter. Robinson and Brown discovered ribosomes in 1953 in plant cell and by Palade in animal cell (1955). Hence, the sequence P - 1, Q - 4, R - 2, S - 3 is correctly matched.
