hey..i believe the answer is choice d i.e E.

ok..permanent maxillary second premolars replace primary maxillary second molars.so if you follow the palmar notation for primary teeth then the primary maxillary left 2nd molar is aasigned by E.but if u follow the universal numbering system then primary second left molar is noted by letter J.

universal numbering system:

for primary dentition:

(maxillary right) (maxillary left)

A B C D E : F G H I J
--------------------
T S R Q P : O N M L K

(mandibular rt) (mandibular left)

For permanent dentition:

1 2 3 4 5 6 7 8 : 9 10 11 12 13 14 15 16
-------------------------------------------------
32 31 30 29 28 27 26 25 : 24 23 22 21 20 19 18 17



Zigmondy-palmar notation :


for primary teeth:

E D B C A : A B C D E
--------------------------
E D B C A : A B C D E

for permanent dentition:

8 7 6 5 4 3 2 1 : 1 2 3 4 5 6 7 8
------------------------------------
8 7 6 5 4 3 2 1 : 1 2 3 4 5 6 7 8

i hope u understand it by now..let me know if u still want further explanation
all the best for the boards..
