Based on this figure, match List-I (Boundary layer zones) with List-II (Types boundary layer)

Question

The development of boundary layer zones labeled P, Q, R and S over a plate is shown in the figure below.        

Based on this figure, match List-I (Boundary layer zones) with List-II (Types boundary layer) and select the correct answer using the codes given below the lists:

List-I                                 List-II

1. P                      1. Transitional
2. Q                     2. Laminar viscous  sub-layer
3. R                     3. Laminar
4. S                      4. Turbulent

Codes:

            A         B         C         D

(a)        3          1          2          4

(b)        3          2          1          4

(c)        4          2          1          3

(d)       4          1          2          3
