Letters of a word have been jumbled up and numbered. Choose the option which gives the correct order of the letters as indicated by the numbers to form the word.

I	A	D	O	H	E	N	S
1	2	3	4	5	6	7	8

Lets check by options:

This order gives: D, A, H, E, S, I, O, N → DAHESION (Not meaningful).

​Option (b): 2, 3, 5, 6, 4, 8, 1, 7​

This order gives: A, D, H, E, O, S, I, N → ADHEOSIN (Not meaningful).

This order gives: A, D, H, E, S, I, O, N → ADHESION (A meaningful word).

This order gives: A, D, H, E, S, O, I, N → ADHESOIN (Not meaningful).​​

Thus, the correct answer is (c).
