Given:
AA, DB, IC, PD, ?
Add consecutive odd numbers starting from 3 in the place value of the first letter and add 1 in the place value of the second letter, to get the required missing term –
AA→A + 3 = D; A + 1 = B→DB
DB→D + 5 = I; B + 1 = C→IC
IC→I + 7 = P; C + 1 = D→PD
PD→P + 9 = Y; D + 1 = E→YE
So, the next term of the series is YE. Hence, the third option is correct.
