Lewis acid strength of group 13 halides follow the order : BCl3 > AlCl3 > GaCl3 > InCl3.
As we move down the group, the size of atom increases, and as a result, the tendency to attract electrons decreases. This leads to a decrease in Lewis acid nature down the group

The correct order of decreasing Lewis acid character amongst the given halides is:
1. AlCl3
2. BCl3
3. GaCl3
4. InCl3
This is because the Lewis acid character of a compound is related to its ability to accept electron pairs. In general, compounds with smaller atomic radii and higher positive charges have greater Lewis acid character.
Aluminum (Al) has a smaller atomic radius and higher positive charge than boron (B), gallium (Ga), and indium (In), making it the strongest Lewis acid amongst the given halides. Therefore, option (a) is correct.
