The option 2 is correct.

Explanation:

Degree of association and van't Hoff factor (i) given by::

\alpha =\frac{(1-i)n}{n-1}

Where :

n = simple molecules of solute in solvent

We have :

Degree of association of phenol= 40% = 0.40

C_6H_5OH\rightarrow \frac{1}{2} (C_6H_5OH)_2

2C_6H_5OH\rightarrow (C_6H_5OH)_2

n = 2

0.40=\frac{(1-i)2}{2-1}

i = 0.8

The option 2 is correct.
