Clair.

Having made a table of women vs characteristics, you can see that:
the "odd man out" for eye color is Clair,
the "odd man out" for hair color is Bianca,
the "odd man out" for height is again Clair.
But we don't know if the "odd man out" has the characteristic or does not have it.
There are 8 possible ways the 3 characteristics could be distributed among the "odd men".  For each of the 8 ways, I added to the table, counting the number of characteristics of each woman.

A 3 2 2 1 2 1 1 0
B 2 1 2 2 1 0 3 1
C 1 2 0 2 2 3 2 2
Any scenario in which one woman has 2 characteristics and another woman has 1 characteristic leads to a logical inconsistency, due to condition 4.  This allows elimination of 6 of the 8 columns:

A 2 1
B 2 0
C 0 3
Either of these leads to the marital choice of Clair.
