How did regents v. bakke change affirmative action policies?

The choices can be found elsewhere and as follows:

-It struck down the use of strict racial quotas. 
-It ruled race could not be factored into admissions. 
-It limited diversity and inequality in the workplace.
-It changed the way applications could be written.

I think the correct answer is the first option. Regents v. Bakke change affirmative action policies by striking down the use of strict racial quotas. 

An attractive economy.
