Correct option is D
First we compare the first letters: All the words start with "D," so we move to the second letter.
· Second letter is same in all so we goes to third letter.
Compare the second letters:
DA ISY, DA RT, DA FFODIL, DA NDY, DA HLIA
Observing the third letters in alphabetical order: F,H,I,N,R
So, the order based on the third letter is:
. DAFFODIL
. DAHLIA
. DAISY
. DANDY
. DART
This is final correct order (3, 5, 1, 4, 2) as well.
Thus, correct option is (d).
